Hello! I’m done with configuring Dockerfile and Docker Compose for my deployment and whenever I test it on the local machine it is perform cool - everything loads properly. But when I try to deploy using ssh, I’m getting this very strange error: error during connect: Post "http://docker.example.c…

[image] nox1os: I’ve added DOCKER_HOST variable to my environment variables, so it uses needed machine as I can see. Just to be 100% sure, for others who may be able to help: so you’re running docker-compose up -d on your local machine to start the services on the remote machine? And all you’…

I am having a similar problem, but with setting a context. I have a Virtualbox VM (Ubuntu 20) running on my Mac. In the VM I have Docker installed rootlessly. The VM is called vmname and the user is username. Virtualbox exposes the VM port 22 on Mac port 3022. Docker client and server are both versi…

OK, as I suspected, I was doing something stupid. For rootless operation, I needed to set the DOCKER_HOST environment variable globally on the Docker server. I added the following line to /etc/environment and restarted the server: DOCKER_HOST=unix:///run/user/1000/docker.sock and everything work…

I didn’t set DOCKER_HOST and it worked for me switching to the rootless context: docker context use rootless If it doesn’t work check the available contexts first docker context ls * in the output means that context is used But if DOCKER_HOST works for you, that is also good :slight_smile: Keep…

OK, it is a confusion between the context on the server and the context on the client. Thanks Ákos, you are right - I don’t need to set DOCKER_HOST on any machine when in rootless mode. On my local development system I can use docker context use <name> to switch between target remote servers. On …

I was getting a similar error using a Mac with macOS Monterrey: Server: ERROR: error during connect: Get "http://docker.example.com/v1.24/info": command [ssh -l myremoteuser -- REMOTE_IP docker system dial-stdio] has exited with exit status 255, please make sure the URL is valid, and Docker 18.09 o…

Do you mean where that default setting is coming from? It is part of the Docker CLI docker/cli/blob/14482589df194a86b2ee07df643ba3277b40df7d/cli/connhelper/connhelper.go#L52 switch scheme := u.Scheme; scheme { case "ssh": sp, err := ssh.Parse…

Thank you for pointing this out. It still does not make sense to me… Why would it try to connect to this non-existing URL?.. A stranger thing is that for me, the error happens intermittently when I try to do compose down on a remote host via docker context. And it happens in the middle of the proc…

So, was anyone able to figure out where the name “docker.example.com” pops out from? Seems to be a mystery…
