nginx-basic-auth


Simple Docker image to provide basic authentication for a single other container.

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
  • REALM (default: "Restricted"): Realm authentication parameter, this is also the message that will appear in the password dialog. The special value off disables the authentication.

    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

nginx: [emerg] host not found in upstream "web" in /etc/nginx/conf.d/auth.conf:80
  • You need to link the container as web (--link foobar:web)

  • SSL is unsupported ATM, but might be available in the near future. For now it might be a suitable solution to use another reverse proxy (e.g. jwilder/nginx-proxy) that acts as a central gateway. You just need to configure the VIRTUAL_HOST env and disable port forwarding.
