Docker查找容器ip报错

OCI runtime exec failed: exec failed: container_linux.go:380: starting container process caused: exec: "ip addr": executable file not found in $PATH: unknown

解决方案：

#进入容器内部，执行apt-get update && apt update && apt install -y iproute2
[root@aliyun ~]# docker exec -it tomcat01 /bin/bash
root@1a8bddcb0fdd:/usr/local/tomcat# apt-get update
