What i have found is when those containers are starting, if I try to do something like sudo ps aux |grep docker inside the container it doesn’t return any output until the containers either start, or it times out.
If the compose file has too many containers in it, then it won’t bring them all up, and i get an error like:
Error response from daemon: failed to create shim task: OCI runtime create failed: runc create failed: unable to start container process: unable to apply cgroup configuration: unable to start unit “docker-eb0b359ce044155417ddeda78fbd628a32aac2327de2ec419a968128f02c3dd9.scope” (properties [{Name:Description Value:“libcontainer container eb0b359ce044155417ddeda78fbd628a32aac2327de2ec419a968128f02c3dd9”} {Name:Slice Value:“system.slice”} {Name:Delegate Value:true} {Name:PIDs Value:@au [3898]} {Name:MemoryAccounting Value:true} {Name:CPUAccounting Value:true} {Name:IOAccounting Value:true} {Name:TasksAccounting Value:true} {Name:DefaultDependencies Value:false}]): Timeout waiting for systemd to create docker-eb0b359ce044155417ddeda78fbd628a32aac2327de2ec419a968128f02c3dd9.scope: unknown
