I am using Yet another docker plugin to configure these slaves. All my jobs are passing successfully on the slave nodes, but I cannot view the workspace from the jenkins UI.

Clash Royale CLAN TAG #URR8PPP ffmpeg and docker result in averror_invaliddata I am running ffmpeg within a docker container, and I am having a problem. I have a wittled-down debug program (listing below) that simply opens (and reads) a test.mp4 I open the file with fopen(), read and print the first 32 bytes. The values agree and are correct whether running in docker or locally. (ie. the file is accessible and readable in the docker container) However, when it gets to avformat_open_input(): Running locally: Works just fine. (and the real program fully decodes it) Running in docker container: The call to avformat_open_input() fails with AVERROR_INVALIDDATA. This is with test.mp4 in the docker directory.

When running a Rails app on a development machine, using Docker, how does once force code changes to be used? I'm using Docker to test out / tweak a Rails app (Helpy), but when I modify the Rails source any changes just get ignored. Even changes to dockker/run.sh or tweaking text on a view.

In this specific case Magento 2 is running on another host in the same private network as the Traefik host.
