Its simple and achieves the same as #250 👍

What is the reason the db is not included and only in the guide?

IMO the jwilder/nginx-proxy:alpine container is really nice - because when redirecting between frontend and backend i dont think it will redirect to the right port? correct me if im wrong.

Otherwise looks good and simple 👍

You could choose MySQL (Percona/MariaDB) or PostGres or SQLite or another one Yii supports; although docs could be more detailed how to use different ones; but the guide also does not cover MySQL installation and setup ie.

It serves as a proxy so it would not redirect. But there are other things to consider:

1. you need to set up hostnames or wildcard DNS (or use .localhost)
2. for the reverse proxy to make sense you should only have one for your Docker machine, which means it should be moved out of the project, which leads to a special setup for configuring Docker networks, this can be painful and error-prone. The best working out-of-the-box solution for local development (not CI) are fixed ports (a different set per project) IMHO

How should we proceed with this? I think there should be some more info about db setup.

Should we add MySQL by default or PostGres or both, or something to the docs how to do that?

Here or in the guide?

Definitely.

MySQL by default + docs about PostgreSQL

Done.

@schmunk42 is there anything missing for this PR to get merged?

[schmunk42]

@machour nothing missing that I could remember...

[samdark]

Merged. Thanks!

Hi, I managed getting advanced template working via docker. But I had to do two more steps next to those documented in start-installation.md, to get apache environment working properly.

1. change mount point to /app/web as in yii2-docker package
2. run apache as UID 1000 to fix asset publishing

Is this supposed to work out of the box? Maybe it's MacOS related issue?
(Tested on fresh docker installation + macos 10.13.6, will check on other systems later)

[schmunk42]

@creep3r Do you run DockerForMac, a VM with docker-machine or something else?

[creep3r]

@schmunk42 Oh yes, Im running docker-machine on virtualbox instance.

[schmunk42]

Would it work for you to give permissions to the asset-folder on the host?

[creep3r]

I did test also on native DockerForMac fresh installation.

1. this persist, because of default yii2-docker apache vhost config
2. it seems to be issue related to docker-machine + virtualbox setup. perhaps could be mentioned in docs?

hi @schmunk42 ,
any advice to write a Dockerfile for console service, i want to run schedule in docker, thanks in advance.

Billy

[schmunk42]

My advice would be to run to scheduler in the same container as your web-server, eg. with supervisord - see https://github.com/dmstr/docker-php-yii2/blob/release/6.x/nginx/Dockerfile-fpm-nginx for an example.

Although this is not 100% Docker-one-service-per-container, we found this to be less error-prone than a separate container - which might be useful for very CPU and/or IO-heavy jobs.

Also keep in mind that you need to export your ENVs for scheduler, see https://github.com/dmstr/phd5-app/blob/master/image-files/usr/local/bin/export-env.sh for an example (it's ugly, but we haven't found anything better yet).

We are running one cronjob once per minute which triggers the scheduler, see also https://github.com/dmstr/phd5-app/blob/master/src/config/schedule.php

Hi, I worked on a docker solution for Yii2 advanced template some time ago.
I needed to work with SSL, thus the script generates self-signed certificates for testing.

Yii2, php7.4-fpm + nginx + postgresql

A problem with my approach is that it requires building the container using a bash script build.sh to generate the certificate and other configurations instead of using docker-compose directly.

Anyway, it works well and from this, I worked on a new solution combined with supervisord for another application. This solution was created for a development environment and uses Redis as a cache DB.
