Example
tempDir := t.TempDir()
p := filepath.Join(tempDir, "Dockerfile")
f, err := os.Create(p)
if err != nil {
t.Fatal(err)
}
defer f.Close()
f.WriteString("FROM alpine:latest")
In this case, we created a Dockerfile in a temporary directory.
Notice how in Go we immediately handle error conditions and defer the closing of the file, which is handled automatically by Go.
