docker: invalid reference format

[m27315]

I'm trying to run a select test in a Docker container. My settings.json looks like:

{
    "phpunit.command": "docker run --rm -t -v ${workspaceFolder}:${workspaceFolder} -u 258006334:258000513 -e XDEBUG_MODE=develop,coverage,debug,trace -e XDEBUG_CONFIG='client_host=10.120.1.1 start_with_request=yes' -e XDEBUG_SESSION=1 -w ${workspaceFolder}/src -e COMPOSER_HOME=${workspaceFolder}/src myimage:9.9.9",
    "phpunit.php": "php",
    "phpunit.phpunit": "vendor/bin/phpunit",
    "phpunit.args": ["--coverage-text", "--coverage-html", "coverage", "--debug"],
    "phpunit.paths": {
        // ${workspaceFolder} (current directory) is mounted to /app
        //"${workspaceFolder}": '/app',
        // ${workspaceFolder} is mapped to /app
    }
}

If I initiate a debugging launch with the following from .vscode/launch.json:

{
    "version": "0.2.0",
    "configurations": [
        {
            "name": "Listen for Xdebug",
            "type": "php",
            "request": "launch",
            "port": 9003
        }
    ]
}

The following appears in the "OUTPUT" pane, when "playing" the desired test:

docker run --rm -t -v /home/me/workspace:/home/me/workspacei -u 258006334:258000513 -e XDEBUG_MODE=develop,coverage,debug,trace -e XDEBUG_CONFIG='client_host=10.120.1.1 start_with_request=yes' -e XDEBUG_SESSION=1 -w /home/me/workspace/src -e COMPOSER_HOME=/home/me/workspace/src myimage:9.9.9 php vendor/bin/phpunit /home/me/workspace/src/tests/application/MyTest.php '--filter=^.*::(testOfSpecialInterest)( with data set .*)?$' '--coverage-text' '--coverage-html=coverage' '--debug' '--teamcity' '--colors=never'

❌ docker: invalid reference format.
See 'docker run --help'.

The curious thing is that I can copy-paste that command directly into any terminal, even VScode's integrated terminal, and it works!

Is there some strange quoting that is occurring but not appearing in the above command?

As a possible workaround, could you make the extension honor phpunit.envVars, like so?

{
    "phpunit.command": "docker run --rm -t -v ${workspaceFolder}:${workspaceFolder} -u 258006334:258000513 -e XDEBUG_MODE -e XDEBUG_CONFIG -e XDEBUG_SESSION -w ${workspaceFolder}/src -e COMPOSER_HOME=${workspaceFolder}/src myimage:9.9.9 bash -c",
    "phpunit.php": "php",
    "phpunit.phpunit": "vendor/bin/phpunit",
    "phpunit.args": ["--coverage-text", "--coverage-html", "coverage", "--debug"],
    "phpunit.envVars": {
        "XDEBUG_MODE": "develop,coverage,debug",
        "XDEBUG_CONFIG": "client_host=10.120.1.1 start_with_request=yes",
        "XDEBUG_SESSION": "1"
    },
    "phpunit.paths": {}
}

This almost works. It does not throw an error. :smile: See:

docker run --rm -t -v /home/me/workspace -u 258006334:258000513 -e XDEBUG_MODE -e XDEBUG_CONFIG -e XDEBUG_SESSION -w /home/me/workspace/src -e COMPOSER_HOME=/home/me/workspace/src myimage:9.9.9 bash -c php vendor/bin/phpunit /home/me/workspace/src/tests/application/MyTest.php '--filter=^.*::(testOfSpecificInterest( with data set .*)?$' '--coverage-text' '--coverage-html=coverage' '--debug' '--teamcity' '--colors=never'

MyTest
  ✅ testIndex 65 ms
🟨 Test 'MyTest::testOfSpecificInterest' ended

Time: 00:00.068, Memory: 22.00 MB
OK (1 test, 4 assertions)

However, it is ignoring the environment variables' values, not injecting them, so it does not stop when it hit my breakpoints. Again, I can run the same command from a terminal, where those env vars are defined like above, and it breaks appropriately.

I've had luck doing it with ini definitions instead of environment vars

    "phpunit.command": "docker-compose exec -T webapp /bin/sh -c",
    "phpunit.phpunit": "./vendor/bin/phpunit",
    "phpunit.args": [
        "-c", "./phpunit.xml",
    ],
    "phpunit.php": "/usr/local/bin/php -d 'zend_extension=xdebug.so' -d 'xdebug.mode=debug,coverage' -d 'xdebug.client_host=host.docker.internal'  -d 'xdebug.client_port=10427'  -d 'xdebug.discover_client_host=1' -d 'xdebug.remote_handler=dbgp'  -d 'xdebug.start_with_request=yes'",
