Using a template without an explicit `user` breaks the workspace container

When starting the example docker-code-server as-is, I get this chdir - no such file or directory error:

I made an issue for it on Github https://github.com/coder/coder/issues/3870 There we found out the HOME environment somehow gets set to the username of user 1000 of the host server: (It's set to /home/skerit when it should be /home/coder)

[skerit@test1 coder]$ env
HOSTNAME=test1
PWD=/home/coder
HOME=/home/skerit
ENTRYPOINTD=/entrypoint.d
LANG=en_US.UTF-8
CODER_AGENT_TOKEN=xxx
TERM=xterm
USER=coder
SHLVL=1
PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin
_=/usr/sbin/env

[skerit@test1 coder]$ env
HOSTNAME=test1
PWD=/home/coder
HOME=/home/skerit
ENTRYPOINTD=/entrypoint.d
LANG=en_US.UTF-8
CODER_AGENT_TOKEN=xxx
TERM=xterm
USER=coder
SHLVL=1
PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin
_=/usr/sbin/env

The workaround for this was to add this to the workspace resource:

resource "docker_container" "workspace" {
  ...
  user = "coder:coder"
}

resource "docker_container" "workspace" {
  ...
  user = "coder:coder"
}

This is on an Arch server, btw 😄

Agent token is invalid inside of workspace container

After finding a good workaround for my issue #3870 (unable open a terminal session, which was because my user inside the workspace containers was wrong), I've got a new problem 😬 My workspace containers are complaining about an invalid agent token:

2022-09-05 16:20:46.013 [INFO]    <./agent/agent.go:450>    (*agent).init    generating host key

I deleted the existing workspaces & templates, restarted coder & made the templates & workspaces again, but it's still happening. Any thoughts on what the issue could be?

Setting up a database in a template

First of all: Coder is running on my server at the office, and I want to host the workspaces on it too with Docker. I've got a PHP project I'm trying to create a template for. It requires a MySQL/MariaDB database to run, so I'm trying to set that up now, but I'm not sure how to go about it. Do I create another terraform resource for it, like:

resource "docker_image" "mariadb" {
  name         = "docker.io/mariadb:latest"
  keep_locally = false
}

resource "docker_container" "mariadb" {
  image = docker_image.mariadb.latest
  name  = "${data.coder_workspace.me.owner}-${data.coder_workspace.me.name}-mariadb"
  ports {
    internal = 3306
    external = 3306
  }
  env = ["MARIADB_ROOT_PASSWORD=elastic"]
}

provider "mysql" {
  endpoint = "localhost:3306"
  username = "root"
  password = "elastic"
}

resource "mysql_database" "app" {
  name = "project_db_name"
}

resource "docker_image" "mariadb" {
  name         = "docker.io/mariadb:latest"
  keep_locally = false
}

resource "docker_container" "mariadb" {
  image = docker_image.mariadb.latest
  name  = "${data.coder_workspace.me.owner}-${data.coder_workspace.me.name}-mariadb"
  ports {
    internal = 3306
    external = 3306
  }
  env = ["MARIADB_ROOT_PASSWORD=elastic"]
}

provider "mysql" {
  endpoint = "localhost:3306"
  username = "root"
  password = "elastic"
}

resource "mysql_database" "app" {
  name = "project_db_name"
}

Or is there another preferred way to do it?
