Deploying NGINX and NGINX Plus on Docker

Deploy NGINX and NGINX Plus as the Docker container.

NGINX Plus, the high‑performance application delivery platform, load balancer, and web server, is available as the Docker container.


  • Docker installation
  • for NGINX Plus: nginx-repo.crt and nginx-repo.key files or JSON Web Token file
  • for NGINX Open Source: Docker Hub account

Building NGINX Plus image for specific OS and architecture

Since NGINX Plus Release 31 you can pull an NIGNX Plus image from the official NGINX Plus Docker registry and upload it to your private registry.

The image may contain a particular version of NGINX Plus or contain a bundle of NGINX Plus and NGINX Agent, and can be targeted for a specific architecture.

Supported NGINX Plus Versions

  • NGINX Plus Release 31
  • NGINX Plus Release 31 with NGINX Agent
  • NGINX Plus Release 30
  • NGINX Plus Release 30 with NGINX Agent

Supported Distributions

  • Alpine (x86_64, aarch64)
  • Debian (x86_64, aarch64)
  • Red Hat Enterprise Linux (x86_64, aarch64)

Supported Image Types

  • base — NGINX Plus only
  • agent — NGINX Plus along with NGINX Agent in a single image
  • rootless-base — NGINX Plus run from nginx user
  • rootless-agent — NGINX Plus with NGINX Agent both run from nginx user

Downloading the NGINX Plus certificate and key or JSON Web Token

Before you get a container image, you should provide the SSL certificate and private key files or JSON Web Token file provided with your NGINX Plus license. These files grant access to the package repository from which the script will download the NGINX Plus package:

  1. Log in to the MyF5 customer portal.
  2. Go to My Products and Plans > Subscriptions.
  3. Select the product subscription.
  4. Download the JSON Web Token file.

  1. Log in to the MyF5 customer portal.
  2. Go to My Products and Plans > Subscriptions.
  3. Select the product subscription.
  4. Download the SSL Certificate and Private Key files.

Set up Docker for NGINX Plus Container Registry

Set up Docker to communicate with the NGINX Container Registry located at

Open the JSON Web Token file previously downloaded from MyF5 customer portal (for example, nginx-repo-12345abc.jwt) and copy its contents.

Log in to the docker registry using the contents of the JSON Web Token file:

docker login --username=<output_of_jwt_token> --password=none

Create a directory and copy your certificate and key to this directory:

mkdir -p /etc/docker/certs.d/
cp <path-to-your-nginx-repo.crt> /etc/docker/certs.d/
cp <path-to-your-nginx-repo.key> /etc/docker/certs.d/

The steps provided are for Linux. For Mac or Windows, see the Docker for Mac or Docker for Windows documentation. For more details on Docker Engine security, you can refer to the Docker Engine Security documentation.

Log in to the docker registry:

docker login

Pulling the image

Next, pull the image you need from

To pull an image, replace <version-tag> with the specific NGINX Plus version and/or OS version you need, for example, r31-ubi-9.

For NGINX Plus, run:

docker pull<version-tag>

For NGINX Plus with NGINX Agent, run:

docker pull<version-tag>

For NGINX Plus installed from nginx user (rootless installation), run:

docker pull<version-tag>

For NGINX Plus with NGINX Agent installed from nginx user (rootless installation), run:

docker pull<version-tag>

Tagging examples:

  • nginx_releaseOS_type: r31-ubi, r31-alpine, r31-debian
  • nginx_releaseOS_typeOS_version: r31-ubi-9, r31-alpine-9.99, r31-debian-sid
  • latest release image gets the OS_type tag: alpine, debian or ubi
  • latest debian-based images also get the short release tag (e.g. R31) and the nginx-plus tag

You can use the Docker registry API to list the available image tags. Replace <path-to-client.key> with the location of your client key and <path-to-client.cert> with the location of your client certificate. The optional jq command is used to format the JSON output for easier reading and requires jq JSON processor to be installed.

curl --key <path-to-your-nginx-repo.key> --cert <path-to-your-nginx-repo.crt> | jq
  "name": "nginx-plus/base",
  "tags": [

Pushing the image to your private registry

After pulling the image, tag it and upload it to your private registry.

Log in to your private registry:

docker login <my-docker-registry>

Tag and push the image. Replace <my-docker-registry> with your registry’s path and <version-tag> with the your NGINX Plus version and/or OS version:

docker tag<version-tag> <my-docker-registry>/nginx-plus/base:<version-tag>
docker push <my-docker-registry>/nginx-plus/base:<version-tag>

Running NGINX Open Source in a Docker Container

You can create an NGINX instance in a Docker container using the NGINX Open Source image from the Docker Hub.

  1. Launch an instance of NGINX running in a container and using the default NGINX configuration with the following command:

    docker run --name mynginx1 -p 80:80 -d nginx


    • mynginx1 is the name of the created container based on the NGINX image

    • the -d option specifies that the container runs in detached mode: the container continues to run until stopped but does not respond to commands run on the command line.

    • the -p option tells Docker to map the ports exposed in the container by the NGINX image (port 80) to the specified port on the Docker host. The first parameter specifies the port in the Docker host, the second parameter is mapped to the port exposed in the container

    The command returns the long form of the container ID: fcd1fb01b14557c7c9d991238f2558ae2704d129cf9fb97bb4fadf673a58580d. This form of ID is used in the name of log files.

  2. Verify that the container was created and is running with the docker ps command:

    $ docker ps
    CONTAINER ID  IMAGE         COMMAND               CREATED         STATUS        ...
    fcd1fb01b145  nginx:latest  "nginx -g 'daemon of  16 seconds ago  Up 15 seconds ...
        ... PORTS              NAMES
        ...>80/tcp mynginx1

This command also allows viewing the port mappings set in the previous step: the PORTS field in the output reports that port 80 on the Docker host is mapped to port 80 in the container.

Creating custom NGINX Plus Docker Image

As NGINX Plus is a commercial offering, NGINX Plus Docker images are not available at Docker Hub, so first you will need to create an NGINX Plus Docker image.

Note: Never upload your NGINX Plus images to a public repository such as Docker Hub. Doing so violates your license agreement.

To generate a custom NGINX Plus image:

  1. Create the Docker build context, or a Dockerfile, for example:

  2. As with NGINX Open Source, default NGINX Plus image has the same default settings:

    • access and error logs are linked to the Docker log collector
    • no volumes are specified: a Dockerfile can be used to create base images from which you can create new images with volumes specified, or volumes can be specified manually:
    VOLUME /usr/share/nginx/html
    VOLUME /etc/nginx
    • no files are copied from the Docker host as a container is created: you can add COPY definitions to each Dockerfile, or the image you create can be used as the basis for another image
  3. Log in to MyF5 Customer Portal and download your nginx-repo.crt and nginx-repo.key files. For a trial of NGINX Plus, the files are provided with your trial package.

  4. Copy the files to the directory where the Dockerfile is located.

  5. Create a Docker image, for example, nginxplus (note the final period in the command).

    docker build  --no-cache --secret id=nginx-key,src=nginx-repo.key --secret id=nginx-crt,src=nginx-repo.crt -t nginxplus .

    The --no-cache option tells Docker to build the image from scratch and ensures the installation of the latest version of NGINX Plus. If the Dockerfile was previously used to build an image without the --no-cache option, the new image uses the version of NGINX Plus from the previously built image from the Docker cache.

  6. Verify that the nginxplus image was created successfully with the docker images command:

    $ docker images nginxplus
    nginxplus   latest  ef2bf65931cf  6 seconds ago  91.2 MB
  7. Create a container based on this image, for example, mynginxplus container:

    docker run --name mynginxplus -p 80:80 -d nginxplus
  8. Verify that the mynginxplus container is up and running with the docker ps command:

    $ docker ps
    CONTAINER ID  IMAGE             COMMAND               CREATED         STATUS        ...
    eb7be9f439db  nginxplus:latest  "nginx -g 'daemon of  1 minute ago    Up 15 seconds ...
        ... PORTS              NAMES
        ...>80/tcp mynginxplus

NGINX Plus containers are controlled and managed in the same way as NGINX Open Source containers.

Managing Content and Configuration Files

Content served by NGINX and NGINX configuration files can be managed in several ways:

  • files are maintained on the Docker host
  • files are copied from the Docker host to a container
  • files are maintained in the container

Maintaining Content and Configuration Files on the Docker Host

When the container is created, you can mount a local directory on the Docker host to a directory in the container. The NGINX image uses the default NGINX configuration, which uses /usr/share/nginx/html as the container’s root directory and puts configuration files in /etc/nginx. For a Docker host with content in the local directory /var/www and configuration files in /var/nginx/conf, run the command:

docker run --name mynginx2 \
   --mount type=bind,source=/var/www,target=/usr/share/nginx/html,readonly \
   --mount type=bind,source=/var/nginx/conf,target=/etc/nginx/conf,readonly \
   -p 80:80 \
   -d nginxplus

Any change made to the files in the local directories /var/www and /var/nginx/conf on the Docker host are reflected in the directories /usr/share/nginx/html and /etc/nginx in the container. The readonly option means these directories can be changed only on the Docker host, not from within the container.

Copying Content and Configuration Files from the Docker Host

Docker can copy the content and configuration files from a local directory on the Docker host during container creation. Once a container is created, the files are maintained by creating a new container when files change or by modifying the files in the container.

A simple way to copy the files is to create a Dockerfile with commands that are run during generation of a new Docker image based on the NGINX image. For the file‑copy (COPY) commands in the Dockerfile, the local directory path is relative to the build context where the Dockerfile is located.

Let’s assume that the content directory is content and the directory for configuration files is conf, both subdirectories of the directory where the Dockerfile is located. The NGINX image has the default NGINX configuration files, including default.conf, in the /etc/nginx/conf.d directory. To use the configuration files from the Docker host only, delete the default files with the RUN command:

FROM nginx
RUN rm /etc/nginx/conf.d/default.conf
COPY content /usr/share/nginx/html
COPY conf /etc/nginx

Create NGINX image by running the command from the directory where the Dockerfile is located. The period (“.”) at the end of the command defines the current directory as the build context, which contains the Dockerfile and the directories to be copied:

docker build -t mynginx_image1 .

Create a container mynginx3 based on the mynginx_image1 image:

docker run --name mynginx3 -p 80:80 -d mynginx_image1

To make changes to the files in the container, use a helper container as described in the next section.

Maintaining Content and Configuration Files in the Container

As SSH cannot be used to access the NGINX container, to edit the content or configuration files directly you need to create a helper container that has shell access. For the helper container to have access to the files, create a new image that has the proper Docker data volumes defined for the image:

  1. Copy nginx content and configuration files and define the volume for the image with the Dockerfile:

    FROM nginx
    COPY content /usr/share/nginx/html
    COPY conf /etc/nginx
    VOLUME /usr/share/nginx/html
    VOLUME /etc/nginx
  2. Create the new NGINX image by running the following command:

    docker build -t mynginx_image2 .
  3. Create an NGINX container mynginx4 based on the mynginx_image2 image:

    docker run --name mynginx4 -p 80:80 -d mynginx_image2
  4. Start a helper container mynginx4_files that has a shell, providing access the content and configuration directories of the mynginx4 container we just created:

    $ docker run -i -t --volumes-from mynginx4 --name mynginx4_files debian /bin/bash


    • the new mynginx4_files helper container runs in the foreground with a persistent standard input (the -i option) and a tty (the -t option). All volumes defined in mynginx4 are mounted as local directories in the helper container.
    • the debian argument means that the helper container uses the Debian image from Docker Hub. Because the NGINX image also uses Debian, it is most efficient to use Debian for the helper container, rather than having Docker load another operating system
    • the /bin/bash argument means that the bash shell runs in the helper container, presenting a shell prompt that you can use to modify files as needed

To start and stop the container, run the commands:

docker start mynginx4_files
docker stop mynginx4_files

To exit the shell but leave the container running, press Ctrl+p followed by Ctrl+q. To regain shell access to a running container, run this command:

docker attach mynginx4_files

To exit the shell and terminate the container, run the exit command.

Managing Logging

You can use default logging or customize logging.

Using Default Logging

By default, the NGINX image is configured to send NGINX access log and error log to the Docker log collector. This is done by linking them to stdout and stderr: all messages from both logs are then written to the file /var/lib/docker/containers/container-ID/container-ID-json.log on the Docker host. The container‑ID is the long‑form ID returned when you create a container. To display the long form ID, run the command:

docker inspect --format '{{ .Id }}' container-name

You can use both the Docker command line and the Docker Engine API to extract the log messages.

To extract log messages from the command line, run the command:

docker logs container-name

To extract log messages using the Docker Remote API, send a GET request using the Docker Unix sock:

curl --unix-sock /var/run/docker-sock http://localhost/containers/container-name/logs?stdout=1&stderr=1

To include only access log messages in the output, include only stdout=1. To limit the output to error log messages, include only stderr=1. For other available options, see Get container logs section of the Docker Engine API documentation.

Using Customized Logging

If you want to configure logging differently for certain configuration blocks (such as server {} and location {}), define a Docker volume for the directory in which to store the log files in the container, create a helper container to access the log files, and use any logging tools. To implement this, create a new image that contains the volume or volumes for the logging files.

For example, to configure NGINX to store log files in /var/log/nginx/log, add a VOLUME definition for this directory to the Dockerfile (provided that content and configuration Files are managed in the container):

FROM nginx
COPY content /usr/share/nginx/html
COPY conf /etc/nginx
VOLUME /var/log/nginx/log

Then you can create an image and use it to create an NGINX container and a helper container that have access to the logging directory. The helper container can have any desired logging tools installed.

Controlling NGINX

Since there is no direct access to the command line of the NGINX container, NGINX commands cannot be sent to a container directly. Instead, signals can be sent to a container via Docker kill command.

To reload the NGINX configuration, send the HUP signal to Docker:

docker kill -s HUP container-name

To restart NGINX, run this command to restart the container:

docker restart container-name
