Docker

Official docker image is available in Docker Hub repository. We also have a some cool examples with Docker Compose template with built-in orchestration and scalability.

Here is a quick example showing how to link a Janus container to a MongoDB container:

1. Start your database:

If you wish to use a database instead of a file system based configuration just start the mongodb container:

$ docker run -d --name janus-database \
                -p 27017:27017 \
                mongo:3.0

1. Configure the update frequency

You should configure how frequently Janus will check for changes on your database. You can set this by changing the cluster configuration:

[cluster]
  UpdateFrequency = "5s"

You can find more information about Janus clusters in the clustering section.

1. Start Janus:

Start a Janus container and link it to your database container (if you are using it), configuring the DATABASE_DSN environment variable with the connection string like mongodb://janus-database:27017/janus:

$ docker run -d --name janus \
                --link janus-database:janus-database \
                -e "DATABASE_DSN=mongodb://janus-database:27017/janus" \
                -p 8080:8080 \
                -p 8443:8443 \
                -p 8081:8081 \
                -p 8444:8444 \
                hellofreshtech/janus

1. Janus is running:

$ curl http://127.0.0.1:8081/
