Caching proxy docker image

Caching proxy docker image

Front your webserver containers with a transparent cache.

What does it do?

This image runs an nginx server as a caching reverse proxy for a given URL. It can be used in conjunction with Traefik in order to transparently cache chosen paths on a backend service.

Usage

The container needs two environment variables:

• UPSTREAM: URL of the upstream service which should be cached
• ALLOWED_ORIGIN: origin URL which is allowed to load the files from this server (header Access-Control-Allowed-Origins) (default *)
• MAX_SIZE: Size of the cache to use (on-disk)
• GZIP: Set to off in order to disable gzip compression (enabled by default)
• PROXY_READ_TIMEOUT: Set the timeout for reading a response from the proxied server (default: 120s)
• PROXY_CACHE_VALID: Set caching time for 200, 301, and 302 responses (disabled by default)

The server will be listening on port 80.

See the supplied docker-compose.yml for an example.
