Redbrick runs a few services in Docker on the following servers:
All Docker files will be
files will be in either in the folder with the docker files or mapped to the
traditional location such as
To Add a service first check the git repo is in a clean state and all changes
are committed. Then create a folder for the new service. It should either be the
services name or purpose, eg
Dockerfile if it is a custom image.
Redbrick uses traefik for ingress to containers. To
allow a container to be added accessed over https first add the following
networks: web: external: true
web is a docker network which should already exist on the host. Then add the
network to the container you want to expose over https.
networks: - web - default
Then Label the container so traefik can route to the right port
labels: - 'traefik.backend=my-awesome-app' - 'traefik.docker.network=web' - 'traefik.frontend.rule=Host:my-awesome-app.zeus.redbrick.dcu.ie' - 'traefik.enable=true' - 'traefik.port=3000'
This exposes the port 3000 on the container at the domain.
must be the containers name. The network is the name of the external network we
specified above. The frontend rule is the domain we want to serve it at, you can
serve it from any subdomain of zeus or add a cname to bind to point to zeus and
traefik.frontend.rule to be that cname.
Redbrick Uses tick for collecting logs. Thankfully docker makes it very easy to add a logging provider. To use tick as a provider add the following to each service
logging: driver: syslog options: syslog-address: 'udp://172.27.0.251:6514' syslog-format: rfc5424micro tag: $SERVICE_NAME
USE VOLUMES. I cant say this enough use a volume if you want your data to persist across service restarts. It is beyond recommended to use a named volume, this avoids the volume getting lost by a stray service outage and makes restoring from backups much easier. You can also write to a folder on disk for your volumes. This isn't the best for databases but works for logs, configs or assets.
So once all put together a docker compose would look like
version: '3' services: redis: image: 'redis:alpine' restart: always volumes: - redis:/data logging: driver: syslog options: syslog-address: 'udp://172.27.0.251:6514' syslog-format: rfc5424micro tag: haste_redis haste: build: . image: redbrick/haste container_name: hastebin depends_on: - redis networks: - web - default labels: - 'traefik.backend=hastebin' - 'traefik.docker.network=web' - 'traefik.frontend.rule=Host:paste.redbrick.dcu.ie' - 'traefik.enable=true' - 'traefik.port=7777' logging: driver: syslog options: syslog-address: 'udp://172.27.0.251:6514' syslog-format: rfc5424micro tag: haste_server networks: web: external: true volumes: redis:
