Change to path.Join is more better?

Or root + "/memory" more single?

Actually I do not think root + "/memory" is a good way. String append via + is not very readable and brings some difficulty to code review. While I think for path, we can use path.Join like @rudyfly suggested. For others, I suggested that we should use format to make it like: fmt.Sprintf("you told me %s", msg).
So I think we had better update this.

@allencloud the config has changed by ContainerManager).Create, like
if config.HostConfig.EnableLxcfs && lxcfs.IsLxcfsEnabled {
config.HostConfig.Binds = append(config.HostConfig.Binds, lxcfs.LxcfsParentDir+":/var/lib/lxc:shared")
sourceDir := lxcfs.LxcfsHomeDir + "/proc/"
destDir := "/proc/"
for _, procFile := range lxcfs.LxcfsProcFiles {
bind := fmt.Sprintf("%s%s:%s%s", sourceDir, procFile, destDir, procFile)
config.HostConfig.Binds = append(config.HostConfig.Binds, bind)
}
}
I don't think we can do validation in the API bridge level.

@fuweid ,do you mean config is merged with something after ContainerManager).Create?

Yes @Ace-Tang . If we can move the merge function into bridge, the validation can be done in bridge, too.
