docker - 无法进入Apache Karaf docker 容器

Question

我已经使用基本镜像apache karaf构建了Dockerfile，但是无法进入Apache Karaf docker容器

[root@HNHC9F2 docker_file]# docker exec -it b8586730289b /opt/karaf/bin/karaf

karaf: There is a Root instance already running with name root and pid 132. If you know what you are doing and want to force the run anyway, export CHECK_ROOT_INSTANCE_RUNNING=false and re run the command.

Answer 1

由于错误提示，您需要导出环境变量CHECK_ROOT_INSTANCE_RUNNING:

docker exec -it b8586730289b bash
export CHECK_ROOT_INSTANCE_RUNNING=false
exit

docker exec -it b8586730289b /opt/karaf/bin/karaf

更新:

如果您只想在容器中放入一个 shell ，那么下面就是所有需要的内容:

docker exec -it b8586730289b bash
