SWR Custom Policies

Custom policies can be created to supplement system-defined policies of SWR.

You can create custom policies in either of the following ways:

• Visual editor: Select cloud services, actions, resources, and request conditions. This does not require knowledge of policy syntax.
• JSON: Create a JSON policy or edit an existing one.

  For details, see Creating a Custom Policy. This section illustrates common custom policies.

Example SWR custom policies

• Example 1: Allowing a user to upload and download images in the test-swr SWR Enterprise Edition instance in the test-namespace namespace

  {
    "Version": "5.0",
    "Statement": [
      {
        "Effect": "Allow",
        "Action": [
          "swr:repository:downloadArtifact",
          "swr:repository:uploadArtifact"
        ],
        "Resource": [
          "swr:*:*:repository:test-swr/test-namespace/*"
        ]
      },
      {
        "Effect": "Allow",
        "Action": [
          "swr:instance:createTempCredential"
        ],
        "Resource": [
          "*"
        ]
      }
    ]
  }

  {
    "Version": "5.0",
    "Statement": [
      {
        "Effect": "Deny",
        "Action": [
          "swr:instance:createReplicationPolicy"
        ],
        "Resource": [
          "swr:*:*:instance:*"
        ],
        "Condition": {
          "StringEquals": {
            "swr:TargetRegion": [
              "${region-b}"
            ],
            "swr:SourceRegion": [
              "${region-a}"
            ]
          }
        }
      },
      {

        "Condition": {
          "ForAnyValue:StringEquals": {
            "swr:SourceUrls": [
              "All repository addresses in region a"
            ],
            "swr:TargetUrls": [
              "All repository addresses in region b"
            ]
          }
        }
