Sebastiaan van Stijn 2c97295ad8 daemon: remove v1 shim configuration for containerd ... This removes the plugin section from the containerd configuration file (`/var/run/docker/containerd/containerd.toml`) that is generated when starting containerd as child process; ```toml [plugins] [plugins.linux] shim = "containerd-shim" runtime = "runc" runtime_root = "/var/lib/docker/runc" no_shim = false shim_debug = true ``` This configuration doesn't appear to be used since commit: 0b14c2b67a, which switched the default runtime to to io.containerd.runc.v2. Note that containerd itself uses `containerd-shim` and `runc` as default for `shim` and `runtime` v1, so omitting that configuration doesn't seem to make a difference. I'm slightly confused if any of the other options in this configuration were actually used: for example, even though `runtime_root` was configured to be `/var/lib/docker/runc`, when starting a container with that coniguration set on docker 19.03, `/var/lib/docker/runc` doesn't appear to exist: ```console $ docker ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 098baa4cb0e7 nginx:alpine "/docker-entrypoint.…" 59 minutes ago Up 59 minutes 80/tcp foo $ ls /var/lib/docker/runc ls: /var/lib/docker/runc: No such file or directory $ ps auxf PID USER TIME COMMAND 1 root 0:00 sh 16 root 0:11 dockerd --debug 26 root 0:09 containerd --config /var/run/docker/containerd/containerd.toml --log-level debug 234 root 0:00 containerd-shim -namespace moby -workdir /var/lib/docker/containerd/daemon/io.containerd.runtime.v1.linux/moby/09 251 root 0:00 nginx: master process nginx -g daemon off; 304 101 0:00 nginx: worker process ... ``` Signed-off-by: Sebastiaan van Stijn <github@gone.nl>		2022-03-07 19:31:24 +01:00
