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 --- roles/openshift_aws/defaults/main.yml | 4 +++ .../tasks/uninstall_security_group.yml | 14 +++++++++ roles/openshift_aws/tasks/uninstall_ssh_keys.yml | 9 ++++++ roles/openshift_aws/tasks/uninstall_vpc.yml | 36 ++++++++++++++++++++++ 4 files changed, 63 insertions(+) create mode 100644 roles/openshift_aws/tasks/uninstall_security_group.yml create mode 100644 roles/openshift_aws/tasks/uninstall_ssh_keys.yml create mode 100644 roles/openshift_aws/tasks/uninstall_vpc.yml (limited to 'roles') diff --git a/roles/openshift_aws/defaults/main.yml b/roles/openshift_aws/defaults/main.yml index efd2468b2..a729e8dbd 100644 --- a/roles/openshift_aws/defaults/main.yml +++ b/roles/openshift_aws/defaults/main.yml @@ -301,3 +301,7 @@ openshift_aws_node_user_data: '' openshift_aws_node_config_namespace: openshift-node openshift_aws_masters_groups: masters,etcd,nodes + +# By default, don't delete things like the shared IAM instance +# profile and uploaded ssh keys +openshift_aws_enable_uninstall_shared_objects: False diff --git a/roles/openshift_aws/tasks/uninstall_security_group.yml b/roles/openshift_aws/tasks/uninstall_security_group.yml new file mode 100644 index 000000000..55d40e8ec --- /dev/null +++ b/roles/openshift_aws/tasks/uninstall_security_group.yml @@ -0,0 +1,14 @@ +--- +- name: delete the node group sgs + oo_ec2_group: + state: absent + name: "{{ item.value.name}}" + region: "{{ openshift_aws_region }}" + with_dict: "{{ openshift_aws_node_security_groups }}" + +- name: delete the k8s sgs for the node group + oo_ec2_group: + state: absent + name: "{{ item.value.name }}_k8s" + region: "{{ openshift_aws_region }}" + with_dict: "{{ openshift_aws_node_security_groups }}" diff --git a/roles/openshift_aws/tasks/uninstall_ssh_keys.yml b/roles/openshift_aws/tasks/uninstall_ssh_keys.yml new file mode 100644 index 000000000..27e42da53 --- /dev/null +++ b/roles/openshift_aws/tasks/uninstall_ssh_keys.yml @@ -0,0 +1,9 @@ +--- +- name: Remove the public keys for the user(s) + ec2_key: + state: absent + name: "{{ item.key_name }}" + region: "{{ openshift_aws_region }}" + with_items: "{{ openshift_aws_users }}" + no_log: True + when: openshift_aws_enable_uninstall_shared_objects | bool diff --git a/roles/openshift_aws/tasks/uninstall_vpc.yml b/roles/openshift_aws/tasks/uninstall_vpc.yml new file mode 100644 index 000000000..ecf39f694 --- /dev/null +++ b/roles/openshift_aws/tasks/uninstall_vpc.yml @@ -0,0 +1,36 @@ +--- +- name: Fetch the VPC for the vpc.id + ec2_vpc_net_facts: + region: "{{ openshift_aws_region }}" + filters: + "tag:Name": "{{ openshift_aws_clusterid }}" + register: vpcout +- debug: + var: vpcout + verbosity: 1 + +- when: vpcout.vpcs | length > 0 + block: + - name: delete the vpc igw + ec2_vpc_igw: + state: absent + region: "{{ openshift_aws_region }}" + vpc_id: "{{ vpcout.vpcs[0].id }}" + register: igw + + - name: delete the vpc subnets + ec2_vpc_subnet: + state: absent + region: "{{ openshift_aws_region }}" + vpc_id: "{{ vpcout.vpcs[0].id }}" + cidr: "{{ item.cidr }}" + az: "{{ item.az }}" + with_items: "{{ openshift_aws_vpc.subnets[openshift_aws_region] }}" + + - name: Delete AWS VPC + ec2_vpc_net: + state: absent + region: "{{ openshift_aws_region }}" + name: "{{ openshift_aws_clusterid }}" + cidr_block: "{{ openshift_aws_vpc.cidr }}" + register: vpc -- cgit v1.2.3
