From a0015f7ead6a89dbb602bc245b51e82cfad66902 Mon Sep 17 00:00:00 2001 From: Joel Diaz Date: Wed, 20 Dec 2017 01:22:23 +0000 Subject: allow uninstalling AWS objects created by prerequisite playbook add deprovisioners/uninstallers for objects created via playbooks/aws/openshift-cluster/prerequisites.yml specifically: security groups, vpcs, and any ssh keys introduce openshift_aws_enable_uninstall_shared_objects to protect AWS objects that would be shared in the case of multiple clusters co-existing in one AWS account. right now it protects the ssh keys, but it can/should be used to protect against deleting the shared IAM instance profile as well. default this variable to False to be on the safe side when uninstalling/deprovisioning. add some documentation on using deprovisioning playbooks --- playbooks/aws/README.md | 14 ++++++++++++++ .../aws/openshift-cluster/uninstall_prerequisites.yml | 6 ++++++ playbooks/aws/openshift-cluster/uninstall_sec_group.yml | 10 ++++++++++ playbooks/aws/openshift-cluster/uninstall_ssh_keypair.yml | 10 ++++++++++ playbooks/aws/openshift-cluster/uninstall_vpc.yml | 10 ++++++++++ 5 files changed, 50 insertions(+) create mode 100644 playbooks/aws/openshift-cluster/uninstall_prerequisites.yml create mode 100644 playbooks/aws/openshift-cluster/uninstall_sec_group.yml create mode 100644 playbooks/aws/openshift-cluster/uninstall_ssh_keypair.yml create mode 100644 playbooks/aws/openshift-cluster/uninstall_vpc.yml (limited to 'playbooks/aws') diff --git a/playbooks/aws/README.md b/playbooks/aws/README.md index d203b9cda..bdc98d1e0 100644 --- a/playbooks/aws/README.md +++ b/playbooks/aws/README.md @@ -198,3 +198,17 @@ At this point your cluster should be ready for workloads.
