ContainerLogs endpoint always returns NULL

[rodrigoaguilera]

When I run

docker run --name test busybox:latest echo hello

I can see the output in the logs with

docker logs test

but running

$logs = $docker->containerLogs('test', ['stdout' => true]);

never returns anything.

I did a bit of debugging of the ContainerLogs.php class and it seems it expects the body to be JSON but the is received as a string
https://github.com/beluga-php/docker-php-api/blob/main/src/Endpoint/ContainerLogs.php#L83

Great findings @rodrigoaguilera ! I'll take a look at it.

This should work using the following:

$logs = $docker->containerLogs('test', ['stdout' => true], \Docker\API\Runtime\Client\Client::FETCH_RESPONSE)->getBody()->getContents();

[rodrigoaguilera]

Since the FETCH_RESPONSE is deprecated now in jane the proper way would be:

use Docker\API\Endpoint\ContainerLogs;

$docker->executeRawEndpoint(new ContainerLogs($containerCreateResult->getId(), ['stdout' => true]))->getBody()->getContents();

See #65

This skips the custom endpoint Docker\Endpoint\ContainerLogs and uses the endpoint from the generated API.
This is because that endpoint returns a content-type application/vnd.docker.multiplexed-stream for me, never a application/vnd.docker.raw-stream like the custom endpoint expects even when I set the header Accept: application/vnd.docker.raw-stream.

I'm reopening because of this issue. The custom AND the jane-generated endpoints seem to be useless to get the logs.
