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). The nginx project started with a strong focus on high concurrency, high performance and low memory usage. It is licensed under the 2-clause BSD-like license and it runs on Linux, BSD variants, Mac OS X, Solaris, AIX, HP-UX, as well as on other *nix flavors. It also has a proof of concept port for Microsoft Window..
$ docker run --name some-nginx -v /some/content:/usr/share/nginx/html:ro -d nginx
Alternatively, a simple Dockerfile
can be used to generate a new image that includes the necessary content (which is a much cleaner solution than the bind mount above):
FROM nginx
COPY static-html-directory /usr/share/nginx/html
Place this file in the same directory as your directory of content ("static-html-directory"), run docker build -t some-content-nginx .
, then start your container:
$ docker run --name some-nginx -d some-content-nginx
$ docker run --name some-nginx -d -p 8080:80 some-content-nginx
Then you can hit http://localhost:8080
or http://host-ip:8080
in your browser.
$ docker run --name some-nginx -v /some/nginx.conf:/etc/nginx/nginx.conf:ro -d nginx
For information on the syntax of the Nginx configuration files, see the official documentation (specifically the Beginner's Guide).
Be sure to include daemon off;
in your custom configuration to ensure that Nginx stays in the foreground so that Docker can track the process properly (otherwise your container will stop immediately after starting)!
If you wish to adapt the default configuration, use something like the following to copy it from a running Nginx container:
$ docker cp some-nginx:/etc/nginx/nginx.conf /some/nginx.conf
As above, this can also be accomplished more cleanly using a simple Dockerfile
:
FROM nginx
COPY nginx.conf /etc/nginx/nginx.conf
Then, build with docker build -t some-custom-nginx .
and run:
$ docker run --name some-nginx -d some-custom-nginx
Out-of-the-box, Nginx doesn't support using environment variables inside most configuration blocks. But envsubst
may be used as a workaround if you need to generate your nginx configuration dynamically before nginx starts.
Here is an example using docker-compose.yml:
image: nginx
volumes:
- ./mysite.template:/etc/nginx/conf.d/mysite.template
ports:
- "8080:80"
environment:
- NGINX_HOST=foobar.com
- NGINX_PORT=80
command: /bin/bash -c "envsubst < /etc/nginx/conf.d/mysite.template > /etc/nginx/conf.d/default.conf && nginx -g 'daemon off;'"
The mysite.template
file may then contain variable references like this :
listen ${NGINX_PORT};
The nginx
images come in many flavors, each designed for a specific use case.
This is the defacto image. If you are unsure about what your needs are, you probably want to use this one. It is designed to be used both as a throw away container (mount your source code and start the container to start your app), as well as the base to build other images off of.
This image is based on the popular Alpine Linux project, available in the alpine
official image. Alpine Linux is much smaller than most distribution base images (~5MB), and thus leads to much slimmer images in general.
This variant is highly recommended when final image size being as small as possible is desired. The main caveat to note is that it does use musl libc instead of glibc and friends, so certain software might run into issues depending on the depth of their libc requirements. However, most software doesn't have an issue with this, so this variant is usually a very safe choice. See this Hacker News comment thread for more discussion of the issues that might arise and some pro/con comparisons of using Alpine-based images.
To minimize image size, it's uncommon for additional related tools (such as git
or bash
) to be included in Alpine-based images. Using this image as a base, add the things you need in your own Dockerfile (see the alpine
image description for examples of how to install packages if you are unfamiliar).
This image is officially supported on Docker version 1.10.3.
Support for older versions (down to 1.6) is provided on a best-effort basis.
Please see the Docker installation documentation for details on how to upgrade your Docker daemon.
