compose

Collection of compose files

Most of the compose files use docker volumes (docker.com) to store persistent data for containers. Only configuration files are binding to the host.

int-docker-net

All the compose files use a default network called int-docker-net.

This references an externally created docker network, created using:

docker network create int-docker-net

Reverse Proxy

The containers get exposed using traefik Proxy (traefik.io).

Only the traefik and portainer services bind directly to the host machine.

Treafik Labels

A list of commonly used labels to expose a service using treafik. These labels are appended to the service configuration in the docker-compose.yml.

    labels:
      # enable treafik discovery for this service
      - traefik.enable=true
      # set entrypoint to http
      #  - traefik.http.routers.<NAME>.entrypoints=web
      # set entrypoint to https
      - traefik.http.routers.<NAME>.entrypoints=websecure
      # bind to a domain or multiple ones using (`DOMAIN`, `DOMAIN2`)
      - traefik.http.routers.<NAME>.rule=Host(`<DOMAIN>`)
      # enable tls
      - traefik.http.routers.<NAME>.tls=true
      # set cert server
      - traefik.http.routers.<NAME>.tls.certresolver=production
    # enable authelia for service, make sure service is in authelia config
    #  - traefik.http.routers.<NAME>.middlewares=authelia@file

This line - traefik.http.routers.changedetection.middlewares=authelia@file references a middleware service authelia. See the traefik/traefik.yml file, under the section # MIDDLEWARES to see how it is configured.

Logging

Disable

Disable logging for a container in the docker compose file.

    logging:
      driver: none

Limit

https://docs.docker.com/compose/compose-file/compose-file-v3/#logging

    logging:
      options:
        max-size: "200k"
        max-file: "10"

The example shown above would store log files until they reach a max-size of 200kB, and then rotate them. The amount of individual log files stored is specified by the max-file value. As logs grow beyond the max limits, older log files are removed to allow storage of new logs.

Delete Logs

Deletes all Logs for this container. Non-reversible. Can break logs.

truncate -s 0 $(docker inspect --format='{{.LogPath}}' <container_name_or_id>)

View Logs and Follow

docker compose logs -f <container name>

Using Graylog

    logging:
      driver: gelf
      options:
        # this references the static ip given to the graylog container
        # port is standard is a gelf udp note, created in web ui
        gelf-address: "udp://172.19.200.1:12201"
        tag: <service-name>

Using Json File

    logging:
      driver: json-file
      options:
        max-size: "200k"
        max-file: "10"
