-We build only MySQL. Our local adjustment to the official image is simply adding `/tmp/mysql` to it. See [build-context/mysql/Dockerfile](build-context/mysql/Dockerfile). We use `/tmp/mysql` to bind-mount a dedicated ZFS dataset for MySQL `tmpdir` location.

 Copy images to target Docker host, that is assuming you deploy to a machine that itself has no network route to reach Docker Hub. Copying in its simplest form involves a local `docker save` and a remote `docker load`. Consider the helper mini-project [quico.space/Quico/copy-docker](https://quico.space/Quico/copy-docker) where [copy-docker.sh](https://quico.space/Quico/copy-docker/src/branch/main/copy-docker.sh) allows the following workflow:
 
 ```
-source "${COMPOSE_ENV}"
+images="$(docker compose --project-name "${COMPOSE_PROJECT}" --file "${COMPOSE_FILE}" --env-file "${COMPOSE_ENV}" --profile 'full' config | grep -Pi -- 'image:' | awk '{print $2}' | sort | uniq)"

-The [example my.cnf](build-context/mysql/docker-data/config/db/my.cnf) config file for MySQL follows [Traccar's recommendation for MySQL](https://www.traccar.org/mysql-optimization/) but uses 512 MiB of RAM instead of Traccar's 3 GiB example. We also add a `tmpdir` whose location gets created in our custom MySQL image up top during [Build](#build). Lastly since we live in a world with MySQL 8.0.30+ we're using `innodb_redo_log_capacity` over Traccar's recommendation (as of Thursday, June 22, 2023) of `innodb_log_file_size`. See also [MySQL 8.0 docs section "Configuring Redo Log Capacity (MySQL 8.0.30 or Higher)"](https://dev.mysql.com/doc/refman/8.0/en/innodb-redo-log.html#innodb-modifying-redo-log-capacity).

 Config `traccar.xml` is a minimal working example file taken from the Traccar Docker image. See [Docker Hub traccar/traccar overview](https://hub.docker.com/r/traccar/traccar) section "Get default traccar.xml". In [our example traccar.xml](build-context/traccar/docker-data/config/traccar.xml) file the default H2 database is replaced with MySQL to match this repo.
