CloudOps Orchestration Service:Manage custom software on multiple ECS instances

1. You can install or uninstall custom software only on ECS instances that reside in virtual private clouds (VPCs). Make sure that the network type of the ECS instances where custom software is to be installed or uninstalled is VPC.

2. Before you install or uninstall custom software on an ECS instance, make sure that a Resource Access Management (RAM) role has been assigned to the instance and the permission policy in the following JSON script is attached to the RAM role. For more information about the authorization method, see Bind an instance RAM role.

Permission policy in a JSON script:

{
    "Version": "1",
    "Statement": [
        {
            "Action": [
                "oos:GetTemplate"
            ],
            "Resource": "*",
            "Effect": "Allow"
        },
        {
            "Action": [
                "oss:GetObject",
                "oss:GetBucketAcl"
            ],
            "Effect": "Allow",
            "Resource": "*"
        }
    ]
}
