Centos7 Docker file mount, no execute permission in container

Run the Nodejs container in Centos7, find that the mounted local directory does not have execute permissions in the container, after various validations and Google search, find the cause of the problem, here to do a record. The reason is that the security module in CENTOS7 selinux has restricted permissions, there are at least the following three ways to resolve the Mount directory does not have permissions issues:

1, when running the container, add privileges to the container:

Example: Docker run-i-T--privileged=true-v/home/docs:/src waterchestnut/nodejs:0.12.0

2. Temporarily close SELinux:

Example: Su-c "Setenforce 0"

After execution:Docker run-i-t-v/home/docs:/src waterchestnut/nodejs:0.12.0

Note: Remember to re-open SELinux, command:su-c "Setenforce 1"

3. Add the SELinux rule to add the directory you want to mount to the whitelist:

Example: Chcon-rt Svirt_sandbox_file_t/home/docs

after execution: Docker run-i-t-v/home/docs:/src waterchestnut/nodejs:0.12.0
