When running multiple instances of the coder/coder devcontainer, the
`postStartCommand` fails with exit code 1:
```
postStartCommand from devcontainer.json failed with exit code 1
Command failed: ./.devcontainer/scripts/post_start.sh
```
`service docker start` returns exit code 1 when Docker is already
running:
| Docker State | Exit Code |
|--------------|-----------|
| Not running | 0 |
| Already running | **1** |
## Fix
Check if Docker is already running before attempting to start it:
```bash
sudo service docker status >/dev/null 2>&1 || sudo service docker start
```

The nix image isn't used because it doesn't work, and we haven't been
updating our "pre-nix" tag since the changes were made. Reverts back to
