If you encounter unexpected problems when using a container, you can log in to the container to debug it.

Log in to the CCE console and click the cluster name to access the cluster console.
In the navigation pane on the left, choose Workloads. Click the name of the target workload to view its pods.
Locate the target pod and choose More > Remote Login in the Operation column.

Figure 1 Accessing a container
In the displayed dialog box, select the container you want to access and the command, and click OK.

Figure 2 Selecting a container and login command
You will be automatically redirected to CloudShell. Then, kubectl is initialized and runs the kubectl exec command to log in to the container.

NOTE:

Wait for 5 to 10 seconds until the kubectl exec command is automatically executed.

Figure 3 CloudShell page

Use kubectl to connect to the cluster. For details, see Connecting to a Cluster Using kubectl.

Run the following command to view the created pod:

kubectl get pod

The example output is as follows:

NAME                               READY   STATUS    RESTARTS       AGE
nginx-59d89cb66f-mhljr             1/1     Running   0              11m

Query the container name in the pod.

kubectl get po nginx-59d89cb66f-mhljr -o jsonpath='{range .spec.containers[*]}{.name}{end}{"\n"}'

The example output is as follows:

container-1

Run the following command to log in to the container-1 container in the nginx-59d89cb66f-mhljr pod:
```
kubectl exec -it nginx-59d89cb66f-mhljr -c container-1 -- /bin/sh
```
To exit the container, run the exit command.
