Open Source Agents being used by SLES-for-SAP
Open Source Agents being used by SLES-for-SAPSUSE is a dedicated Open Source provider. SUSE tends to uses agents being published Upstream in the ClusterLabs Open Source project.
The Open Source agents being published via SLES-for-SAP are the only ones with SUSE support. Customers have evergrowing requirements. SUSE and AWS work on improving the agents.
This page lists the ClusterLabs agents as well as experimental agents without support.

| STONITH agent | /usr/lib64/stonith/plugins/external/ec2 | ec2 | 34a217f on ~ Aug 6, 2018 |
Stops and monitors EC2 instances. This version is filtering the EC2 commands which has the following advantages
|
Cosmetic: The --text option in AWS CLI command is missing. This would lower the risk of configuration errors with the AWS profile SUSE Bug 1106700: - AWS: ec2 agent has fixes implemented upstream |
| Move Overlay IP | /usr/lib/ocf/resource.d/suse/aws-vpc-move-ip | aws-vpc-move-ip | 7ac4653Sept. 4, 2018 | Reassign an AWS Overlay IP address in a routing table |
Heads up: This agent is not compatible to the proprietary agent from SUSE. SUSE uses a parameter with the name address. The upstream version uses the parameter name ip. I haven't yet been able to make this agent work in a SUSE cluster :-( |
| Route 53 | /usr/lib/ocf/resource.d/heartbeat/aws-vpc-route53 | aws-vpc-route53.in | 7632a85 ~August 6, 2018 | Update a record in an AWS Route 53 hosted zone (DNS server) |
calls of ec2metadata will fail if the AWS user data contains strings like "local-ipv4". This can happen in specific AWS Quickstart implementations Bug 1106706 - AWS: Route 53 agent has fixes implemented upstream |
There is an ongoing discussion about updating the agents. Here are some experimental agents without any SUSE support.

| Move Overlay IP | /usr/lib/ocf/resource.d/suse/aws-vpc-move-ip | ...soon here... | . | Reassign an AWS Overlay IP address in a routing table | New monitoring doesn't work when a cluster node rejoins a cluster. Use the old monitoring mode by adding the parametermonapi="true" to the primitive. Monitoring function got updated. New mode works. No parameter needed |
| Route 53 | /usr/lib/ocf/resource.d/heartbeat/aws-vpc-route53 | aws-vpc-route53 | 319ba06 on 2 Jul, 2018 | Update a record in an AWS Route 53 hosted zone (DNS server) | calls of ec2metadata will fail if the AWS user data contains strings like "local-ipv4". This can happen in specific AWS Quickstart implementations. The implementation ofec2metadata has been replaced with a more specific implementation |
