Other containers on the server can be executed normally. The Gitlab works correctly, but it cannot be modified. ### Steps to reproduce No attempt to reproduce. ### What is the current *bug* behavior? Gitlab containers cannot be maintained by "Docker exec". ### What is the expected *correct* behavior? The Gitlab container can be maintained normally using "Docker exec". ### Relevant logs and/or screenshots Just docker log： [docker.log](/uploads/a40e6e8419ddf2d7b535f74d406128e1/docker.log) #### Results of GitLab environment info docker info： ```yaml Containers: 1 Running: 1 Paused: 0 Stopped: 0 Images: 29 Server Version: 17.12.0-ce Storage Driver: aufs Root Dir: /opt/lib/docker/aufs Backing Filesystem: xfs Dirs: 214 Dirperm1 Supported: true Logging Driver: json-file Cgroup Driver: cgroupfs Plugins: Volume: local Network: bridge host macvlan null overlay Log: awslogs fluentd gcplogs gelf journald json-file logentries splunk syslog Swarm: inactive Runtimes: runc Default Runtime: runc Init Binary: docker-init containerd version: 89623f28b87a6004d4b785663257362d1658a729 runc version: b2567b37d7b75eb4cf325b77297b140ea686ce8f init version: 949e6fa Security Options: apparmor seccomp Profile: default Kernel Version: 4.4.0-62-generic Operating System: Ubuntu 16.04.2 LTS OSType: linux Architecture: x86_64 CPUs: 4 Total Memory: 7.796GiB Name: git.cqrd.com ID: SC55:OWCD:2AR5:ZQUA:IZ3L:U6HT:MRBW:WOYE:HGOQ:JSZE:OGCX:CK5S Docker Root Dir: /opt/lib/docker Debug Mode (client): false Debug Mode (server): false HTTP Proxy: http://172.17.18.80:8080 HTTPS Proxy: http://172.17.18.80:8080 No Proxy: .x,hub.com,h.com,.cae.com Registry: https://index.docker.io/v1/ Labels: Experimental: false Insecure Registries: h.com hub.com hub.x 127.0.0.0/8 Registry Mirrors: https://mirror.cae.com/ Live Restore Enabled: true WARNING: No swap limit support ``` docker version: ```yaml Client: Version: 17.12.0-ce API version: 1.35 Go version: go1.9.2 Git commit: c97c6d6 Built: Wed Dec 27 20:11:19 2017 OS/Arch: linux/amd64 Server: Engine: Version: 17.12.0-ce API version: 1.35 (minimum version 1.12) Go version: go1.9.2 Git commit: c97c6d6 Built: Wed Dec 27 20:09:53 2017 OS/Arch: linux/amd64 Experimental: false ``` docker service status: ```yaml ● docker.service - Docker Application Container Engine Loaded: loaded (/lib/systemd/system/docker.service; enabled; vendor preset: enabled) Drop-In: /etc/systemd/system/docker.service.d └─proxy.conf Active: active (running) since Fri 2018-07-06 18:26:42 CST; 2 months 6 days ago Docs: https://docs.docker.com Main PID: 1207 (dockerd) Tasks: 63 Memory: 666.4M CPU: 12h 42min 45.760s CGroup: /system.slice/docker.service ├─1207 /usr/bin/dockerd -H fd:// ├─1319 docker-containerd --config /var/run/docker/containerd/containerd.toml ├─2720 /usr/bin/docker-proxy -proto tcp -host-ip 0.0.0.0 -host-port 443 -container-ip 172.172.172.2 -container-port 443 ├─2744 /usr/bin/docker-proxy -proto tcp -host-ip 0.0.0.0 -host-port 80 -container-ip 172.172.172.2 -container-port 80 ├─2762 /usr/bin/docker-proxy -proto tcp -host-ip 0.0.0.0 -host-port 22 -container-ip 172.172.172.2 -container-port 22 └─2772 docker-containerd-shim -namespace moby -workdir /opt/lib/docker/containerd/daemon/io.containerd.runtime.v1.linux/moby/52b11c202caebc ``` server info ```yaml Linux git.cqrd.com 4.4.0-62-generic #83-Ubuntu SMP Wed Jan 18 14:10:15 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux ``` gitlab version:`GitLab Community Edition 11.0.0` gitlab container status： ```yaml 52b11c202cae gitlab/gitlab-ce:11.0.0-ce.0 "/assets/wrapper" 7 weeks ago Up 7 weeks (healthy) 0.0.0.0:22->22/tcp, 0.0.0.0:80->80/tcp, 0.0.0.0:443->443/tcp gitlab ```
