Types

type Commit

type Commit struct {
	ID       string // ID is the actual commit ID of external tool.
	Expected string // Expected is the commit ID of external tool expected by dockerd as set at build time.
}

Commit holds the Git-commit (SHA1) that a binary was built from, as reported in the version-string of external tools, such as containerd, or runC.
