Docker Nginx Basic Auth - Simple Authentication Proxy

Lightweight nginx reverse proxy with HTTP basic authentication for securing Docker containers and web applications.

Quickstart

docker run -d --name web dockercloud/hello-world
docker run -d -p 80:80 --link web:web --name auth beevelop/nginx-basic-auth

Try accessing and logging in with username foo and password bar.

Advanced

docker run -d \
           -e HTPASSWD='foo:$apr1$odHl5EJN$KbxMfo86Qdve2FH4owePn.' \
           -e FORWARD_PORT=1337 \
           --link web:web -p 8080:80 \
           --name auth \
           beevelop/nginx-basic-auth

Use single quotes to prevent unwanted interpretation of $ signs!

Configuration

• HTPASSWD (default: foo:$apr1$odHl5EJN$KbxMfo86Qdve2FH4owePn.): Will be written to the .htpasswd file on launch (non-persistent)
• FORWARD_PORT (default: 80): Port of the source container that should be forwarded
• FORWARD_HOST (default: web): Hostname of the source container that should be forwarded

  The container does not need any volumes to be mounted! Nonetheless you will find all interesting files at /etc/nginx/*.

Multiple Users

Multiple Users are possible by separating the users by newline. To pass the newlines properly you need to use Shell Quoting (like $'foo\nbar'):

docker run -d --link web:web --name auth \
           -e HTPASSWD=$'foo:$apr1$odHl5EJN$KbxMfo86Qdve2FH4owePn.\ntest:$apr1$LKkW8P4Y$P1X/r2YyaexhVL1LzZAQm.' \
           beevelop/nginx-basic-auth

results in 2 users (foo:bar and test:test).

Troubleshooting

Error: nginx: [emerg] host not found in upstream "web"

• Ensure you link the container as web using --link foobar:web

Limitations

• SSL/HTTPS is not currently supported
• For SSL requirements, consider using jwilder/nginx-proxy as a central gateway with VIRTUAL_HOST environment variable
