docker-runc not installed on system

问题

Docker build时Dockerfile有RUN命令执行报错shim error: docker-runc not installed on system，如下：

解决方法

修改/etc/docker/daemon.json，添加正面内容

{"runtimes": {"docker-runc": {"path": "/usr/libexec/docker/docker-runc-current"}},"add-runtime": "docker-runc=/usr/libexec/docker/docker-runc-current","default-runtime": "docker-runc"
}

保存退出，然后重启Docker即可

systemctl daemon-reload
systemctl start docker
