映射卷时，docker容器无法启动

Question

When I run this command to run docker(Docker version 18.09.6, build 481bc77156):

sudo docker run -p 18084:8070 -v /opt/dabai/app/config-center/docker-apollo/apollo-portal/target/apollo-portal-1.4.0-github:/apollo-portal:rw apollo-portal

The output is:

[daai@iZ3refzweg1d9dh94t9Z ~]$ sudo docker run -p 18084:8070 -v /opt/dabai/app/config-center/docker-apollo/apollo-portal/target/apollo-portal-1.4.0-github:/apollo-portal:rw apollo-portal

Failed to start
Fri May 31 07:59:16 UTC 2019 Failed to start apollo-portal.jar, return code: 1

I use this command to check the docker's log:

docker logs ce518631ced

the output is the same.How do i detect where is the problem is? By the way, when I remove the volume mapping, the container starts up successfully.

Answer 1

Copy container files to local machine to replace old mapping folder could solve this problem.

docker cp 12ba0764beff:/apollo-portal /opt/dabai/app/docker/apollo/apollo-portal

12ba0764beff is the container id.start docker with mapping:

sudo docker run -p 18084:8070 -v /apollo-portal /opt/dabai/app/docker/apollo/apollo-portal:/apollo-portal:rw apollo-portal
