The alternative text of the image was useless, and we were depending on
an external server in order to display it. Furthermore, the text inside
the image was pretty small.
So we're displaying the output of the command as plain text.
There was a typo where we said we were creating the containers but we
were building the image.
While none of these commands are necessary because they're run
automatically when first running the `db:create` rake task, I think it's
better to show them separately, since the `build` command might be used
to rebuild the image, and running the `create` command separately makes
it easier to know what's going on.
We're also removing the "start database service" step, since it's
automatically started because the app service depends on it.
Finally, we're updating one command for macOS.
Docker and Docker Compose are included in most Linux distributions, and
we don't know whether the windows error we talked about is still
relevant in 2024. In any case, the Docker documentation to install
windows is a better resource for that than our documentation.
We're also using the same Docker commands for every operating system.
We were following it about half of the time and we even added it to our
former `.mdlrc` file. However, for some reason, MDL doesn't detect this
rule when specified in the `.mdlrc` file, so we didn't notice we weren't
following it in many cases.
Now that we're using a style file to configure MDL, we can enable this
rule again and apply it, since now MDL correctly includes it in its
report.
Note that, in order to have some consistency, we're always writing
"Consul Democracy", instead of using capital letters sometimes (but not
always), like we did until now.
We were using the SSH URL in the Docker documentation, while using the
HTTPS URL everywhere else. The HTTPS URL is the right one in this case
because it's meant for people who won't have write access to the
repository.
