Docker Data Volume permissions

Run the Nodejs container in CentOS7, find the mounted local directory does not execute permissions in the container, after various authentication and Google search, found the cause of the problem, here to do a record. The reason is that the security module in CentOS7 selinux the permissions, at least in the following three ways to solve the problem of a mounted directory without permissions:

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: Then remember to reopen SELinux, command: su-c "Setenforce 1"

3, add the SELinux rule to add the directory you want to mount to the white list:

Example:chcon-rt svirt_sandbox_file_t/home/docs

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