Accessing the Multicloud Object Gateway from the terminal

Use this information to access the Multicloud Object Gateway from the terminal.

Before you begin

A running Fusion Data Foundation Platform.
Download the MCG command-line interface for easier management.
```
subscription-manager repos --enable=rh-odf-4-for-rhel-8-x86_64-rpms
```
```
yum install mcg
```
Note: Specify the appropriate architecture for enabling the repositories using the subscription manager.
- For IBM Power, use the following command:
```
subscription-manager repos --enable=rh-odf-4-for-rhel-8-ppc64le-rpms
```
- For IBM Z infrastructure, use the following command:
```
subscription-manager repos --enable=rh-odf-4-for-rhel-8-s390x-rpms
```
Alternatively, you can install the MCG package from the RPMs found at Download Red Hat OpenShift Data Foundation page.
Note: Choose the correct Product Variant according to your architecture.

Procedure

Run the describe command to view information about the Multicloud Object Gateway (MCG) endpoint, including its access key (AWS_ACCESS_KEY_ID value) and secret access key (AWS_SECRET_ACCESS_KEY value).

oc describe noobaa -n openshift-storage

Example output, where (1) is the access key (AWS_ACCESS_KEY_ID value), (2) is the secret access key (AWS_SECRET_ACCESS_KEY value), and (3) is the MCG endpoint

    Lets get started:

    1. Connect to Management console:

      Read your mgmt console login information (email & password) from secret: "noobaa-admin".

        kubectl get secret noobaa-admin -n openshift-storage -o json | jq '.data|map_values(@base64d)'

      Open the management console service - take External IP/DNS or Node Port or use port forwarding:

        kubectl port-forward -n openshift-storage service/noobaa-mgmt 11443:443 &
        open https://localhost:11443

    2. Test S3 client:

      kubectl port-forward -n openshift-storage service/s3 10443:443 &how 
(1)
      NOOBAA_ACCESS_KEY=$(kubectl get secret noobaa-admin -n openshift-storage -o json | jq -r '.data.AWS_ACCESS_KEY_ID|@base64d')
(2)
      NOOBAA_SECRET_KEY=$(kubectl get secret noobaa-admin -n openshift-storage -o json | jq -r '.data.AWS_SECRET_ACCESS_KEY|@base64d')
      alias s3='AWS_ACCESS_KEY_ID=$NOOBAA_ACCESS_KEY AWS_SECRET_ACCESS_KEY=$NOOBAA_SECRET_KEY aws --endpoint https://localhost:10443 --no-verify-ssl s3'
      s3 ls

Note: The output from the oc describe noobaa command lists the internal and external DNS names that are available. When using the internal DNS, the traffic is free. The external DNS uses Load Balancing to process the traffic, and therefore has a cost per hour.
