Creating a Custom Policy

Creating a Custom Policy
Custom policies can be created to supplement the system-defined policies of MRS. For the actions that can be added to custom policies, see Permissions Policies and Supported Actions > Introduction in MapReduce Service API Reference.
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: Edit JSON policies from scratch or based on an existing policy.
Custom policy modifications do not take effect immediately. You need to wait about 15 minutes.
The following section contains examples of common MRS custom policies.
Example Custom Policies
- Example 1: Allowing users to create MRS clusters only
{ "Version": "1.1", "Statement": [ { "Effect": "Allow", "Action": [ "mrs:cluster:create", "ecs:*:*", "bms:*:*", "evs:*:*", "vpc:*:*", "smn:*:*" ] } ] } - Example 2: Allowing users to resize an MRS cluster
{ "Version": "1.1", "Statement": [ { "Effect": "Allow", "Action": [ "mrs:cluster:resize" ] } ] } - Example 3: Allowing users to create a cluster, create and execute a job, and delete a single job, but denying cluster deletion
{ "Version": "1.1", "Statement": [ { "Effect": "Allow", "Action": [ "mrs:cluster:create", "mrs:job:submit", "mrs:job:delete" ] }, { "Effect": "Deny", "Action": [ "mrs:cluster:delete" ] } ] } - Example 4: Allowing users to create an ECS cluster with the minimum permission
- If you need a key pair when creating a cluster, add the following permissions: ecs:serverKeypairs:get and ecs:serverKeypairs:list.
- Add the kms:cmk:list permission when encrypting data disks during cluster creation.
- Add the mrs:alarm:subscribe permission to enable the alarm function during cluster creation.
- Add the rds:instance:list permission to use external data sources during cluster creation.
{ "Version": "1.1", "Statement": [ { "Effect": "Allow", "Action": [ "mrs:cluster:create" ] }, { "Effect": "Allow", "Action": [ "ecs:cloudServers:updateMetadata", "ecs:cloudServerFlavors:get", "ecs:cloudServerQuotas:get", "ecs:servers:list", "ecs:servers:get", "ecs:cloudServers:delete", "ecs:cloudServers:list", "ecs:serverInterfaces:get", "ecs:serverGroups:manage", "ecs:servers:setMetadata", "ecs:cloudServers:get", "ecs:cloudServers:create" ] }, { "Effect": "Allow", "Action": [ "vpc:securityGroups:create", "vpc:securityGroupRules:delete", "vpc:vpcs:create", "vpc:ports:create", "vpc:securityGroups:get", "vpc:subnets:create", "vpc:privateIps:delete", "vpc:quotas:list", "vpc:networks:get", "vpc:publicIps:list", "vpc:securityGroups:delete", "vpc:securityGroupRules:create", "vpc:privateIps:create", "vpc:ports:get", "vpc:ports:delete", "vpc:publicIps:update", "vpc:subnets:get", "vpc:publicIps:get", "vpc:ports:update", "vpc:vpcs:list" ] }, { "Effect": "Allow", "Action": [ "evs:quotas:get", "evs:types:get" ] }, { "Effect": "Allow", "Action": [ "bms:serverFlavors:get" ] } ] } - Example 5: Allowing users to create a BMS cluster with the minimum permission
- If you need a key pair when creating a cluster, add the following permissions: ecs:serverKeypairs:get and ecs:serverKeypairs:list.
- Add the kms:cmk:list permission when encrypting data disks during cluster creation.
- Add the mrs:alarm:subscribe permission to enable the alarm function during cluster creation.
- Add the rds:instance:list permission to use external data sources during cluster creation.

- If you need a key pair when creating a cluster, add the following permissions: ecs:serverKeypairs:get and ecs:serverKeypairs:list.
- Add the kms:cmk:list permission when encrypting data disks during cluster creation.
- Add the mrs:alarm:subscribe permission to enable the alarm function during cluster creation.
- Add the rds:instance:list permission to use external data sources during cluster creation.
