What is NGINX Open Source?

NGINX (pronounced "engine-x") is an open source reverse proxy server for HTTP, HTTPS, SMTP, POP3 and IMAP protocols, as well as a load balancer, HTTP cache, and a web server (origin server).


$ docker run --name nginx bitnami/nginx:latest

Docker Compose

$ curl -sSL > docker-compose.yml
$ docker-compose up -d

Why use Bitnami Images?

  • Bitnami closely tracks upstream source changes and promptly publishes new versions of this image using our automated systems.

How to deploy NGINX Open Source in Kubernetes?

Deploying Bitnami applications as Helm Charts is the easiest way to get started with our applications on Kubernetes. Read more about the installation in the Bitnami NGINX Open Source Chart GitHub repository.

Bitnami containers can be used with Kubeapps for deployment and management of Helm Charts in clusters.

Why use a non-root container?

Non-root container images add an extra layer of security and are generally recommended for production environments. However, because they run as a non-root user, privileged tasks are typically off-limits. Learn more about non-root containers in our docs.

Supported tags and respective Dockerfile links

Learn more about the Bitnami tagging policy and the difference between rolling tags and immutable tags in our documentation page.

Get this image

The recommended way to get the Bitnami NGINX Open Source Docker Image is to pull the prebuilt image from the Docker Hub Registry.

$ docker pull bitnami/nginx:latest

To use a specific version, you can pull a versioned tag. You can view the list of available versions in the Docker Hub Registry.

$ docker pull bitnami/nginx:[TAG]

If you wish, you can also build the image yourself.

$ docker build -t bitnami/nginx:latest ''

Hosting a static website

This NGINX Open Source image exposes a volume at /app. Content mounted here is served by the default catch-all server block.

$ docker run -v /path/to/app:/app bitnami/nginx:latest

or by modifying the docker-compose.yml file present in this repository:

      - /path/to/app:/app

Accessing your server from the host

To access your web server from your host machine you can ask Docker to map a random port on your host to ports 8080 and 8443 exposed in the container.

$ docker run --name nginx -P bitnami/nginx:latest

Run docker port to determine the random ports Docker assigned.

$ docker port nginx
8080/tcp ->

You can also manually specify the ports you want forwarded from your host to the container.

$ docker run -p 9000:8080 bitnami/nginx:latest

Access your web server in the browser by navigating to http://localhost:9000.


Adding custom server blocks

The default nginx.conf includes server blocks placed in /opt/bitnami/nginx/conf/server_blocks/. You can mount a my_server_block.conf file containing your custom server block at this location.

For example, in order add a server block for

Step 1: Write your my_server_block.conf file with the following content.

server {
  root /app;
  index index.htm index.html;

Step 2: Mount the configuration as a volume.

$ docker run --name nginx \
  -v /path/to/my_server_block.conf:/opt/bitnami/nginx/conf/server_blocks/my_server_block.conf:ro \

or by modifying the docker-compose.yml file present in this repository:

      - /path/to/my_server_block.conf:/opt/bitnami/nginx/conf/server_blocks/my_server_block.conf:ro

Using custom SSL certificates

NOTE: The steps below assume that you are using a custom domain name and that you have already configured the custom domain name to point to your server.

Step 1: Prepare your certificate files

In your local computer, create a folder called certs and put your certificates files. Make sure you rename both files to server.crt and server.key respectively:

$ mkdir -p /path/to/nginx-persistence/certs
$ cp /path/to/certfile.crt /path/to/nginx-persistence/certs/server.crt
$ cp /path/to/keyfile.key  /path/to/nginx-persistence/certs/server.key

Step 2: Provide a custom Server Block for SSL connections

Write your my_server_block.conf file with the SSL configuration and the relative path to the certificates:

  server {
    listen       8443 ssl;

    ssl_certificate      bitnami/certs/server.crt;
    ssl_certificate_key  bitnami/certs/server.key;

    ssl_session_cache    shared:SSL:1m;
    ssl_session_timeout  5m;

    ssl_ciphers  HIGH:!aNULL:!MD5;
    ssl_prefer_server_ciphers  on;

    location / {
      root   html;
      index  index.html index.htm;

Step 3: Run the NGINX Open Source image and open the SSL port

Run the NGINX Open Source image, mounting the certificates directory from your host.

$ docker run --name nginx \
  -v /path/to/my_server_block.conf:/opt/bitnami/nginx/conf/server_blocks/my_server_block.conf:ro \
  -v /path/to/nginx-persistence/certs:/certs \

or by modifying the docker-compose.yml file present in this repository:

    - /path/to/nginx-persistence/certs:/certs
    - /path/to/my_server_block.conf:/opt/bitnami/nginx/conf/server_blocks/my_server_block.conf:ro

Full configuration

The image looks for configurations in /opt/bitnami/nginx/conf/nginx.conf. You can overwrite the nginx.conf file using your own custom configuration file.

$ docker run --name nginx \
  -v /path/to/your_nginx.conf:/opt/bitnami/nginx/conf/nginx.conf:ro \

or by modifying the docker-compose.yml file present in this repository:

      - /path/to/your_nginx.conf:/opt/bitnami/nginx/conf/nginx.conf:ro

Reverse proxy to other containers

NGINX can be used to reverse proxy to other containers using Docker's linking system. This is particularly useful if you want to serve dynamic content through an NGINX frontend. To do so, add a server block like the following in the /opt/bitnami/nginx/conf/server_blocks/ folder:

server {
    access_log /opt/bitnami/nginx/logs/yourapp_access.log;
    error_log /opt/bitnami/nginx/logs/yourapp_error.log;

    location / {
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header HOST $http_host;
        proxy_set_header X-NginX-Proxy true;

        proxy_pass http://[your_container_alias]:[your_container_port];
        proxy_redirect off;

Further Reading:


The Bitnami NGINX Open Source Docker image sends the container logs to the stdout. To view the logs:

$ docker logs nginx

or using Docker Compose:

$ docker-compose logs nginx

You can configure the containers logging driver using the --log-driver option if you wish to consume the container logs differently. In the default configuration docker uses the json-file driver.

Understand the structure of this image

The Bitnami NGINX Open Source Docker image is built using a Dockerfile with the structure below:

FROM bitnami/minideb-extras-base
# Install required system packages and dependencies
RUN install_packages xxx yyy zzz
RUN . /opt/bitnami/scripts/ && component_unpack "nginx" "a.b.c-0"
COPY rootfs /
RUN /opt/bitnami/scripts/nginx/
EXPOSE 8080 8443
USER 1001
ENTRYPOINT [ "/opt/bitnami/scripts/nginx/" ]
CMD [ "/opt/bitnami/scripts/nginx/" ]

The Dockerfile has several sections related to:

  • Components installation
  • Components static configuration
  • Environment variables
  • Volumes
  • Ports to be exposed
  • Working directory and user
    • Note that once the user is set to 1001, unprivileged commands cannot be executed any longer.
  • Entrypoint and command
    • Take into account that these actions are not executed until the container is started.

Customize this image

The Bitnami NGINX Open Source Docker image is designed to be extended so it can be used as the base image for your custom web applications.

Note: Read the previous section to understand the Dockerfile structure before extending this image.

Extend this image

Before extending this image, please note there are certain configuration settings you can modify using the original image:

If your desired customizations cannot be covered using the methods mentioned above, extend the image. To do so, create your own image using a Dockerfile with the format below:

FROM bitnami/nginx
## Put your customizations below

Here is an example of extending the image with the following modifications:

  • Install the vim editor
  • Modify the NGINX configuration file
  • Modify the ports used by NGINX
  • Change the user that runs the container
FROM bitnami/nginx
LABEL maintainer "Bitnami <>"

## Install 'vim'
USER 0 # Required to perform privileged actions
RUN install_packages vim
USER 1001 # Revert to the original non-root user

## Modify 'worker_connections' on NGINX config file to '512'
RUN sed -i -r "s#(\s+worker_connections\s+)[0-9]+;#\1512;#" /opt/bitnami/nginx/conf/nginx.conf

## Modify the ports used by NGINX by default
ENV NGINX_HTTP_PORT_NUMBER=8181 # It is also possible to change this environment variable at runtime
EXPOSE 8181 8143

## Modify the default container user
USER 1002

Based on the extended image, you can use a Docker Compose file like the one below to add other features:

  • Add a custom server block
  • Add custom certificates
  • Clone your web application and serve it through NGINX
version: '2'

    build: .
      - '80:8181'
      - '443:8443'
      - cloner
      - ./config/my_server_block.conf:/opt/bitnami/nginx/conf/conf.d/server_blocks/my_server_block.conf:ro
      - ./certs:/certs
