Hello everyone,
I wanted to share a useful snippet of Go code that I’ve found helpful in my project. This demonstrates how you can execute a command in an Anbox container using the Anbox Cloud AMS SDK.
First, we assume that you have a valid instance of the clientImpl (which implements the client interface in the Anbox Cloud AMS SDK).
c := &clientImpl{}
Next, you should define the container ID where you want to run the command. For example:
id := "your-container-id"
Then, define the command details that you want to run in the container.
details := &api.ContainerExecPost{
Command: []string{"ls", "-la"},
Environment: map[string]string{"HOME": "/root"},
WaitForWS: true,
Interactive: true,
}
Here, we want to run the ls -la command.
Prepare your input/output streams. In this example, we are redirecting the output to the console.
stdin, _ := io.Pipe()
args := &ContainerExecArgs{
Stdin: stdin,
Stdout: os.Stdout, // redirecting the command output to the console
Stderr: os.Stderr, // redirecting the errors to the console
Control: func(conn *websocket.Conn) {
defer conn.Close()
for {
_, _, err := conn.ReadMessage()
if err != nil {
log.Println("error reading websocket message:", err)
break
}
}
},
DataDone: make(chan bool),
}
Now we are ready to run the command in the container:
op, err := c.ExecuteContainer(id, details, args)
if err != nil {
log.Fatalf("failed to execute command in container: %s", err)
}
err = op.Wait()
if err != nil {
log.Fatalf("operation failed: %s", err)
}
This block of code will execute the command in the container and wait for the operation to complete.
I hope you find this useful! Let me know if you have any questions or suggestions.
Best,
Paolo
