Docker
Utilizing BunkerWeb as a Docker container offers a convenient and straightforward approach for testing and utilizing the solution, particularly if you are already familiar with Docker technology.
To facilitate your Docker deployment, we provide readily available prebuilt images on Docker Hub, supporting multiple architectures. These prebuilt images are optimized and prepared for use on the following architectures:
- x64 (64-bit)
- x86
- armv8 (ARM 64-bit)
- armv7 (ARM 32-bit)
By accessing these prebuilt images from Docker Hub, you can quickly pull and run BunkerWeb within your Docker environment, eliminating the need for extensive configuration or setup processes. This streamlined approach allows you to focus on leveraging the capabilities of BunkerWeb without unnecessary complexities.
Whether you're conducting tests, developing applications, or deploying BunkerWeb in production, the Docker containerization option provides flexibility and ease of use. Embracing this method empowers you to take full advantage of BunkerWeb's features while leveraging the benefits of Docker technology.
docker pull bunkerity/bunkerweb:1.5.10
Docker images are also available on GitHub packages and can be downloaded using the ghcr.io
repository address :
docker pull ghcr.io/bunkerity/bunkerweb:1.5.10
Alternatively, if you prefer a more hands-on approach, you have the option to build the Docker image directly from the source. Building the image from source gives you greater control and customization over the deployment process. However, please note that this method may take some time to complete, depending on your hardware configuration.
While the image is being built, you can take a moment to relax and enjoy a cup of coffee ☕, as the process may require some patience. Once the image is successfully built, you can proceed to deploy and utilize BunkerWeb within your Docker environment. This method allows you to tailor the image to your specific requirements and ensures a more personalized deployment of BunkerWeb.
So, whether you choose to use the ready-to-use prebuilt images or embark on the journey of building the image from source, BunkerWeb in Docker provides you with the flexibility and options to seamlessly integrate it into your environment.
git clone https://github.com/bunkerity/bunkerweb.git && \
cd bunkerweb && \
docker build -t my-bunkerweb -f src/bunkerweb/Dockerfile .
Docker integration key concepts are :
- Environment variables to configure BunkerWeb
- Scheduler container to store configuration and execute jobs
- Networks to expose ports for clients and connect to upstream web services
When integrating BunkerWeb with Docker, there are key concepts to keep in mind, ensuring a smooth and efficient deployment:
-
Environment variables: BunkerWeb can be easily configured using environment variables. These variables allow you to customize various aspects of BunkerWeb's behavior, such as network settings, security options, and other parameters.
-
Scheduler container: To effectively manage the configuration and execution of jobs, BunkerWeb utilizes a dedicated container called the scheduler.
-
Networks: Docker networks play a vital role in the integration of BunkerWeb. These networks serve two main purposes: exposing ports to clients and connecting to upstream web services. By exposing ports, BunkerWeb can accept incoming requests from clients, allowing them to access the protected web services. Additionally, by connecting to upstream web services, BunkerWeb can efficiently route and manage the traffic, providing enhanced security and performance.
Database backend
Please be aware that our instructions assume you are using SQLite as the default database backend, as configured by the DATABASE_URI
setting. However, we understand that you may prefer to utilize alternative backends for your Docker integration. If that is the case, rest assured that other database backends are still possible. See docker-compose files in the misc/integrations folder folder of the repository for more information.
Environment variables
Settings are passed to BunkerWeb using Docker environment variables :
...
services:
mybunker:
image: bunkerity/bunkerweb:1.5.10
labels:
- "bunkerweb.INSTANCE=yes"
environment:
- MY_SETTING=value
- ANOTHER_SETTING=another value
...
Please note that the bunkerweb.INSTANCE
is mandatory to make sure the scheduler can detect BunkerWeb instance(s).
Full list
For the complete list of environment variables, see the settings section of the documentation.
Scheduler
The scheduler is executed in its own container which is also available on Docker Hub :
docker pull bunkerity/bunkerweb-scheduler:1.5.10
Alternatively, you can build the Docker image directly from the source (less coffee ☕ needed than BunkerWeb image) :
git clone https://github.com/bunkerity/bunkerweb.git && \
cd bunkerweb && \
docker build -t my-scheduler -f src/scheduler/Dockerfile .
A volume is needed to store the SQLite database that will be used by the scheduler :
...
services:
bw-scheduler:
image: bunkerity/bunkerweb-scheduler:1.5.10
volumes:
- bw-data:/data
...
volumes:
bw-data:
Using local folder for persistent data
The scheduler runs as an unprivileged user with UID 101 and GID 101 inside the container. The reason behind this is security : in case a vulnerability is exploited, the attacker won't have full root (UID/GID 0) privileges. But there is a downside : if you use a local folder for the persistent data, you will need to set the correct permissions so the unprivileged user can write data to it. Something like that should do the trick :
mkdir bw-data && \
chown root:101 bw-data && \
chmod 770 bw-data
Alternatively, if the folder already exists :
chown -R root:101 bw-data && \
chmod -R 770 bw-data
If you are using Docker in rootless mode or podman, UIDs and GIDs in the container will be mapped to different ones in the host. You will first need to check your initial subuid and subgid :
grep ^$(whoami): /etc/subuid && \
grep ^$(whoami): /etc/subgid
For example, if you have a value of 100000, the mapped UID/GID will be 100100 (100000 + 100) :
mkdir bw-data && \
sudo chgrp 100100 bw-data && \
chmod 770 bw-data
Or if the folder already exists :
shell
sudo chgrp -R 100100 bw-data && \
chmod -R 770 bw-data
When using Docker-based integrations, the scheduler will need to access the Docker API to get things working which is defined using the DOCKER_HOST
environment variable.
Docker API access and security
Due to Docker's limitations in supporting fine-grained authorizations, it's important to be aware of the potential security risks associated with accessing the API directly. Accessing the Docker API can pose a threat, as an attacker with API access can potentially obtain root privileges on the host machine. For more detailed information on this topic, we encourage you to refer to the provided link (here).
To mitigate these risks, we strongly advise against directly mounting the socket file located at /var/run/docker.sock
within the BunkerWeb container. Instead, we recommend employing an alternative approach that enhances security. One such approach involves using a "proxy" container, such as tecnativa/docker-socket-proxy
, which acts as an intermediary and allows only necessary API calls.
By adopting this proxy container strategy, you can establish a more secure communication channel with the Docker API, minimizing the potential attack surface and enhancing overall system security.
You will need to create the Docker API proxy container, mount the socket and set the DOCKER_HOST
environment variable to use the Docker API proxy :
...
services:
bw-scheduler:
image: bunkerity/bunkerweb-scheduler:1.5.10
env:
- DOCKER_HOST=tcp://bw-docker:2375
...
bw-docker:
image: tecnativa/docker-socket-proxy:nightly
volumes:
- /var/run/docker.sock:/var/run/docker.sock
environment:
- CONTAINERS=1
- LOG_LEVEL=warning
...
Docker socket in rootless mode
If you are using Docker in rootless mode, you will need to replace the mount of the docker socket with the following value : $XDG_RUNTIME_DIR/docker.sock:/var/run/docker.sock:ro
.
Networks
By default, BunkerWeb container is listening (inside the container) on 8080/tcp for HTTP and 8443/tcp for HTTPS.
Privileged ports in rootless mode or when using podman
If you are using Docker in rootless mode and want to redirect privileged ports (< 1024) like 80 and 443 to BunkerWeb, please refer to the prerequisites here.
If you are using podman you can lower the minimum number for unprivileged ports :
sudo sysctl net.ipv4.ip_unprivileged_port_start=1
The typical BunkerWeb stack when using the Docker integration contains the following containers :
- BunkerWeb
- Scheduler
- Docker socket proxy
- Your services
For defense in depth purposes, we strongly recommend to create at least three different Docker networks :
bw-services
: for BunkerWeb and your web servicesbw-universe
: for BunkerWeb and schedulerbw-docker
: for scheduler and the Docker API proxy
To secure the communication between the scheduler and BunkerWeb API, it is important to authorize API calls. You can use the API_WHITELIST_IP
setting to specify allowed IP addresses and subnets. It is strongly recommended to use a static subnet for the bw-universe
network to enhance security. By implementing these measures, you can ensure that only authorized sources can access the BunkerWeb API, reducing the risk of unauthorized access or malicious activities:

Linux
Supported Linux distributions for BunkerWeb (amd64/x86_64 and arm64/aarch64 architectures) include:
- Debian 12 "Bookworm"
- Ubuntu 22.04 "Jammy"
- Ubuntu 24.04 "Noble"
- Fedora 40
- Red Hat Enterprise Linux (RHEL) 8.9
- Red Hat Enterprise Linux (RHEL) 9.4
Please ensure that you have NGINX 1.26.2 installed before installing BunkerWeb. For all distributions, except Fedora, it is mandatory to use prebuilt packages from the official NGINX repository. Compiling NGINX from source or using packages from different repositories will not work with the official prebuilt packages of BunkerWeb. However, you have the option to build BunkerWeb from source.
The first step is to add NGINX official repository :
sudo apt install -y curl gnupg2 ca-certificates lsb-release debian-archive-keyring && \
curl https://nginx.org/keys/nginx_signing.key | gpg --dearmor \
| sudo tee /usr/share/keyrings/nginx-archive-keyring.gpg >/dev/null && \
echo "deb [signed-by=/usr/share/keyrings/nginx-archive-keyring.gpg] \
http://nginx.org/packages/debian `lsb_release -cs` nginx" \
| sudo tee /etc/apt/sources.list.d/nginx.list
You should now be able to install NGINX 1.26.2 :
sudo apt update && \
sudo apt install -y nginx=1.26.2-1~$(lsb_release -cs)
Testing/dev version
If you use the testing
or dev
version, you will need to add the force-bad-version
directive to your /etc/dpkg/dpkg.cfg
file before installing BunkerWeb.
echo "force-bad-version" | sudo tee -a /etc/dpkg/dpkg.cfg
Optional step : if you want to automatically enable the setup wizard when BunkerWeb is installed, export the following variable :
export UI_WIZARD=1
And finally install BunkerWeb 1.5.10 :
curl -s https://repo.bunkerweb.io/install/script.deb.sh | sudo bash && \
sudo apt update && \
sudo -E apt install -y bunkerweb=1.5.10
To prevent upgrading NGINX and/or BunkerWeb packages when executing apt upgrade
, you can use the following command :
sudo apt-mark hold nginx bunkerweb
The first step is to add NGINX official repository :
sudo apt install -y curl gnupg2 ca-certificates lsb-release ubuntu-keyring && \
curl https://nginx.org/keys/nginx_signing.key | gpg --dearmor \
| sudo tee /usr/share/keyrings/nginx-archive-keyring.gpg >/dev/null && \
echo "deb [signed-by=/usr/share/keyrings/nginx-archive-keyring.gpg] \
http://nginx.org/packages/ubuntu `lsb_release -cs` nginx" \
| sudo tee /etc/apt/sources.list.d/nginx.list
You should now be able to install NGINX 1.26.2 :
sudo apt update && \
sudo apt install -y nginx=1.26.2-1~$(lsb_release -cs)
Testing/dev version
If you use the testing
or dev
version, you will need to add the force-bad-version
directive to your /etc/dpkg/dpkg.cfg
file before installing BunkerWeb.
echo "force-bad-version" | sudo tee -a /etc/dpkg/dpkg.cfg
Optional step : if you want to automatically enable the setup wizard when BunkerWeb is installed, export the following variable :

sudo apt update && \
sudo -E apt install -y bunkerweb=1.5.10
To prevent upgrading NGINX and/or BunkerWeb packages when executing apt upgrade
, you can use the following command :
sudo apt-mark hold nginx bunkerweb
Fedora Update Testing
If you can't find the NGINX version listed in the stable repository, you can enable the updates-testing
repository :
sudo dnf config-manager --set-enabled updates-testing
Fedora already provides NGINX 1.26.2 that we support :
sudo dnf install -y nginx-1.26.2
Optional step : if you want to automatically enable the setup wizard when BunkerWeb is installed, export the following variable :
export UI_WIZARD=1
And finally install BunkerWeb 1.5.10 :
curl -s https://repo.bunkerweb.io/install/script.rpm.sh | \
sed 's/yum install -y pygpgme --disablerepo='\''bunkerity_bunkerweb'\''/yum install -y python-gnupg/g' | \
sed 's/pypgpme_check=`rpm -qa | grep -qw pygpgme`/python-gnupg_check=`rpm -qa | grep -qw python-gnupg`/g' | sudo bash && \
sudo dnf makecache && \
sudo -E dnf install -y bunkerweb-1.5.10
To prevent upgrading NGINX and/or BunkerWeb packages when executing dnf upgrade
, you can use the following command :
sudo dnf versionlock add nginx && \
sudo dnf versionlock add bunkerweb
The first step is to add NGINX official repository. Create the following file at /etc/yum.repos.d/nginx.repo
:
[nginx-stable]
name=nginx stable repo
baseurl=http://nginx.org/packages/centos/$releasever/$basearch/
gpgcheck=1
enabled=1
gpgkey=https://nginx.org/keys/nginx_signing.key

baseurl=http://nginx.org/packages/mainline/centos/$releasever/$basearch/
gpgcheck=1
enabled=0
gpgkey=https://nginx.org/keys/nginx_signing.key
module_hotfixes=true
You should now be able to install NGINX 1.26.2 :
sudo dnf install nginx-1.26.2
Optional step : if you want to automatically enable the setup wizard when BunkerWeb is installed, export the following variable :
export UI_WIZARD=1
And finally install BunkerWeb 1.5.10 :
sudo dnf install -y epel-release && \
curl -s https://repo.bunkerweb.io/install/script.rpm.sh | sudo bash && \
sudo dnf check-update && \
sudo -E dnf install -y bunkerweb-1.5.10
To prevent upgrading NGINX and/or BunkerWeb packages when executing dnf upgrade
, you can use the following command :
sudo dnf versionlock add nginx && \
sudo dnf versionlock add bunkerweb
The configuration of BunkerWeb is done by editing the /etc/bunkerweb/variables.env
file :
MY_SETTING_1=value1
MY_SETTING_2=value2
...
BunkerWeb is managed using systemctl :
- Check BunkerWeb status :
systemctl status bunkerweb
- Start it if it's stopped :
systemctl start bunkerweb
- Stop it if it's started :
systemctl stop bunkerweb
- Reload it to apply new configuration :
systemctl reload bunkerweb
- And restart it :
systemctl restart bunkerweb
Docker autoconf
Docker integration
The Docker autoconf integration is an "evolution" of the Docker one. Please read the Docker integration section first if needed.
An alternative approach is available to address the inconvenience of recreating the container every time there is an update. By utilizing another image called autoconf, you can automate the real-time reconfiguration of BunkerWeb without the need for container recreation.
To leverage this functionality, instead of defining environment variables for the BunkerWeb container, you can add labels to your web application containers. The autoconf image will then listen for Docker events and seamlessly handle the configuration updates for BunkerWeb.
This "automagical" process simplifies the management of BunkerWeb configurations. By adding labels to your web application containers, you can delegate the reconfiguration tasks to autoconf without the manual intervention of container recreation. This streamlines the update process and enhances convenience.
By adopting this approach, you can enjoy real-time reconfiguration of BunkerWeb without the hassle of container recreation, making it more efficient and user-friendly.
Multisite mode
The Docker autoconf integration implies the use of multisite mode. Please refer to the multisite section of the documentation for more information.
Database backend
Please be aware that our instructions assume you are using MariaDB as the default database backend, as configured by the DATABASE_URI
setting. However, we understand that you may prefer to utilize alternative backends for your Docker integration. If that is the case, rest assured that other database backends are still possible. See docker-compose files in the misc/integrations folder folder of the repository for more information.
To enable automated configuration updates, include an additional container called bw-autoconf
in the stack. This container hosts the autoconf service, which manages dynamic configuration changes for BunkerWeb. To support this functionality, use a dedicated "real" database backend (e.g., MariaDB, MySQL, or PostgreSQL) for synchronized configuration storage. By integrating bw-autoconf
and a suitable database backend, you establish the infrastructure for seamless automated configuration management in BunkerWeb.

Database in the bw-docker
network
The database container is intentionally not included in the bw-universe
network. It is used by the bw-autoconf
and bw-scheduler
containers rather than directly by BunkerWeb. Therefore, the database container is part of the bw-docker
network, which enhances security by making external access to the database more challenging. This deliberate design choice helps safeguard the database and strengthens the overall security perspective of the system.
Using Docker in rootless mode
If you are using Docker in rootless mode, you will need to replace the mount of the docker socket with the following value : $XDG_RUNTIME_DIR/docker.sock:/var/run/docker.sock:ro
.
Once the stack is set up, you will be able to create the web application container and add the settings as labels using the "bunkerweb." prefix in order to automatically set up BunkerWeb :
version: "3.5"
services:
myapp:
image: mywebapp:4.2
networks:
bw-services:
aliases:
- myapp
labels:
- "bunkerweb.MY_SETTING_1=value1"
- "bunkerweb.MY_SETTING_2=value2"
networks:
bw-services:
external: true
name: bw-services
Kubernetes
To automate the configuration of BunkerWeb instances in a Kubernetes environment, the autoconf service serves as an Ingress controller. It configures the BunkerWeb instances based on Ingress resources and also monitors other Kubernetes objects, such as ConfigMap, for custom configurations.
For an optimal setup, it is recommended to define BunkerWeb as a DaemonSet, which ensures that a pod is created on all nodes, while the autoconf and scheduler are defined as single replicated Deployment.
Given the presence of multiple BunkerWeb instances, it is necessary to establish a shared data store implemented as a Redis service. This Redis service will be utilized by the instances to cache and share data among themselves. Further information about the Redis settings can be found here.
Database backend
Please be aware that our instructions assume you are using MariaDB as the default database backend, as configured by the DATABASE_URI
setting. However, we understand that you may prefer to utilize alternative backends for your Docker integration. If that is the case, rest assured that other database backends are still possible. See docker-compose files in the misc/integrations folder folder of the repository for more information.
Clustered database backends setup are out-of-the-scope of this documentation.
Please ensure that both the scheduler and autoconf services have access to the Kubernetes API. It is recommended to utilize RBAC authorization for this purpose.
Additionally, it is crucial to set the KUBERNETES_MODE
environment variable to yes
when utilizing the Kubernetes integration. This variable is mandatory for proper functionality.

Once the BunkerWeb Kubernetes stack is successfully set up and operational (refer to the autoconf logs for detailed information), you can proceed with deploying web applications within the cluster and declaring your Ingress resource.
It is important to note that the BunkerWeb settings need to be specified as annotations for the Ingress resource. For the domain part, please use the special value "bunkerweb.io". By including the appropriate annotations, you can configure BunkerWeb accordingly for the Ingress resource.

Swarm
Docker autoconf
The Swarm integration is similar to the Docker autoconf one (but with services instead of containers). Please read the Docker autoconf integration section first if needed.
To enable automatic configuration of BunkerWeb instances, the autoconf service requires access to the Docker API. This service listens for Docker Swarm events, such as service creation or deletion, and seamlessly configures the BunkerWeb instances in real-time without any downtime. It also monitors other Swarm objects, such as configs, for custom configurations.
Similar to the Docker autoconf integration, configuration for web services is defined using labels that start with the bunkerweb prefix.
For an optimal setup, it is recommended to schedule the BunkerWeb service as a global service on all nodes, while the autoconf, scheduler, and Docker API proxy services should be scheduled as single replicated services. Please note that the Docker API proxy service needs to be scheduled on a manager node unless you configure it to use a remote API (which is not covered in the documentation).
Since multiple instances of BunkerWeb are running, a shared data store implemented as a Redis service must be created. These instances will utilize the Redis service to cache and share data. Further details regarding the Redis settings can be found here.
As for the database volume, the documentation does not specify a specific approach. Choosing either a shared folder or a specific driver for the database volume is dependent on your unique use-case and is left as an exercise for the reader.
Database backend
Please be aware that our instructions assume you are using MariaDB as the default database backend, as configured by the DATABASE_URI
setting. However, we understand that you may prefer to utilize alternative backends for your Docker integration. If that is the case, rest assured that other database backends are still possible. See docker-compose files in the misc/integrations folder folder of the repository for more information.
Clustered database backends setup are out-of-the-scope of this documentation.
Here is the stack boilerplate that you can deploy using docker stack deploy

Swarm mandatory setting
Please note that the SWARM_MODE=yes
environment variable is mandatory when using the Swarm integration.
Once the BunkerWeb Swarm stack is set up and running (see autoconf and scheduler logs for more information), you will be able to deploy web applications in the cluster and use labels to dynamically configure BunkerWeb :
version: "3.5"
services:
myapp:
image: mywebapp:4.2
networks:
- bw-services
deploy:
placement:
constraints:
- "node.role==worker"
labels:
- "bunkerweb.MY_SETTING_1=value1"
- "bunkerweb.MY_SETTING_2=value2"
networks:
bw-services:
external: true
name: bw-services
Microsoft Azure
Recommended VM size
Please be aware while you choose the SKU of the VM. You must select a SKU compatible with Gen2 VM and we recommend starting at B2s or Ds2 series for optimal use.
You can easily deploy BunkerWeb on your Azure subscription in several ways:
- Azure CLI in Cloud Shell
- Azure ARM Template
- Azure portal via the Marketplace
Create a resource group. Replace value RG_NAME
az group create --name "RG_NAME" --location "LOCATION"
Create a VM with Standard_B2s
SKU in the location of the resource group. Replace values RG_NAME
, VM_NAME
, VNET_NAME
, SUBNET_NAME
az vm create --resource-group "RG_NAME" --name "VM_NAME" --image bunkerity:bunkerweb:bunkerweb:latest --accept-term --generate-ssh-keys --vnet-name "VNET_NAME" --size Standard_B2s --subnet "SUBNET_NAME"
Full command. Replace values RG_NAME

Permissions requirement
To deploy a ARM template, you need write access on the resources you're deploying and access to all operations on the Microsoft.Resources/deployments resource type. To deploy a virtual machine, you need Microsoft.Compute/virtualMachines/write and Microsoft.Resources/deployments/* permissions. The what-if operation has the same permission requirements.
Deploy the ARM Template:
Login in Azure portal.
Get BunkerWeb from the Create resource menu.
You can also go through the Marketplace.
You can access the setup wizard by browsing the https://your-ip-address/setup
URI of your virtual machine.
