Docker坑系列

1. container无法删除

表现为一个运行中的容器，stop和kill没效果，查看/var/log/messages日志如下:

Mar 14 18:24:23 localhost dockerd: time="2017-03-14T18:24:23.005216354+08:00" level=warning msg="container kill failed because of 'container not found' or 'no such process': Cannot kill container 2d3fd2ca48a42a2e4c56cf08abfe120cdc9a07c50a02b025c5e651ad0f8adb3e: rpc error: code = 2 desc = containerd: container not found"
Mar 14 18:24:33 localhost dockerd: time="2017-03-14T18:24:33.005531933+08:00" level=info msg="Container 2d3fd2ca48a4 failed to exit within 10 seconds of kill - trying direct SIGKILL"

systemctl restart docker重启解决。

2. docker run报错

执行sudo docker run -dit --restart=unless-stopped -p 8080:8080 rancher/server时报错：

docker: Error response from daemon: mkdir /var/lib/docker/overlay/22ec70f56f655c703dbfa7731e7596f7adab16688e5f7e0f5f80631e1b6282c1-init/merged/dev/shm: invalid argument.
See 'docker run --help'.

看到这篇帖子, 应该是跟storage drivers有关，再参考官方文档, CentOS 推荐devicemapper

vi /etc/docker/daemon.json 添加如下内容：

{
  "storage-driver": "devicemapper"
}

重启docker即可。

3. sbt-native-packager push镜像报错

重启大法好！systemctl restart docker.service 搞定！
