- Remove "demo", "production" containers and have just one.
- Remove dependency on config.toml and inline config to env vars.
- Have a single idempotent instal+upgrade+run command that eliminates
the need for manual upgrade steps.
- Remove `.sh` install scripts.
- Simplify and clean up install and update docs.
The 'hostname' field in the docker-compose file is later used in Listmonk to generate the 'Message-Id' of each mail. The hostname is used as the id-right section of 'Message-Id'.
According to RFC 2822 3.6.4, id-right = dot-atom-text / no-fold-literal / obs-id-right
Also, Rspamd has a spam filtering field 'MID_RHS_NOT_FQDN' which defaults to a 1.0 score.
This commit suggests an FQDN in the docker-compose file, which is guaranteed to meet the requirement.
- Add a shell script to orchestrate a production setup with
`docker-compose`. The script fetches config and `docker-compose.yml`
from the `master` branch, generates a secure password, performs DB
migrations and starts the container services.
- Add a health check for Postgres container service in `docker-compose.yml`.
- Add cusotm `container_name` for services inside `docker-compose`.
This is helpful to check the status of containers in the install shell script.
This PR adds `config-demo.toml` to `Dockerfile` which uses the db host
`demo-db`. This is more suited for demo setups. For normal docker installations
the db host is changed back to `db` which is a better sane default.
Reworded `INSTALL.md` and `README.md` for more clarity on docker
installation and configuration.
