Docker 容器没有ip addr 命令：exec ip addr 报错

柔情只为你懂 2023-09-23 19:12 115阅读 0赞

exec failed: exec failed… exec: “ip”(Docker容器没有ip addr命令：exec ip addr 报错)

#### 1、报错信息1： ####

OCI runtime exec failed: exec failed: unable to start container process: exec: "ip": executable file not found in $PATH: unknown

#### 2、报错原因： ####

我们下载的某个镜像(例如tomcat镜像)是精简版的，利用这个镜像去打开一个容器的时候发现没有ip addr这个命令。

#### 3、解决报错1的方法：安装工具 iproute2 ####

进入容器内部(比如tomcat01容器)
