Docker

Docker images are created with sbt-native-packager and published on DockerHub at walfie/gbf-raidfinder.

Pulling

You can pull the latest pre-built tagged image using:

docker pull walfie/gbf-raidfinder

Running

The container exposes port 9000 as its HTTP port, and the application expects various environment variables to be set:

# Twitter API keys used by Twitter4J
oauth.consumerKey=*****
oauth.consumerSecret=*****
oauth.accessToken=*****
oauth.accessTokenSecret=*****

# Optional Redis connection string
GBF_REDIS_URL=redis://user:pass@host:1234

These can be set with the -e option or by saving them in a file and using --env-file.

For example, if the above was saved as the file /path/to/env, and you wanted to run the app on port 5555 of the host machine:

docker run -p 5555:9000 --env-file /path/to/env walfie/gbf-raidfinder

The above would bind port 9000 of the application to port 5555 of the host machine, and set environment variables based on the file.

This is equivalent to:

docker run -p 5555:9000 \
  -e oauth.consumerKey=***** \
  -e oauth.consumerSecret=***** \
  -e oauth.accessToken=***** \
  -e oauth.accessTokenSecret=***** \
  -e GBF_REDIS_URL=redis://user:pass@host:1234 \
  walfie/gbf-raidfinder

On success, the application will be available on port 5555 of the host machine.

You can also add the -d and --restart unless-stopped to run it in the background:

docker run -d -p 5555:9000 --restart unless-stopped --env-file /path/to/env walfie/gbf-raidfinder

For instructions on running it behind an nginx proxy, you can refer to this comment by Laforeta.

Building

If you want to build the image yourself instead of using the pre-built one on DockerHub, you can run the following in the root directory:

sbt docker:publish
