From c9688b8571500878d10632740d14b4b9fb9dcc7f Mon Sep 17 00:00:00 2001 From: Jan Chaloupka Date: Fri, 31 Mar 2017 13:31:42 +0200 Subject: Refactor etcd roles - introduce block and simplify when conditions - introduce config.yml so the self-standing etcd role can be run (e.g. to test etcd cluster deployment) - remove empty task files - skip dependency on openshift_etcd_ca - replace cert paths with their appropriate variables --- playbooks/byo/openshift-etcd/config.yml | 14 ++++ roles/etcd/defaults/main.yaml | 1 - roles/etcd/files/etcdctl.sh | 11 --- roles/etcd/meta/main.yml | 1 + roles/etcd/tasks/etcdctl.yml | 6 +- roles/etcd/tasks/main.yml | 112 +++++++++++++-------------- roles/etcd/templates/etcd.docker.service | 4 +- roles/etcd/templates/etcdctl.sh.j2 | 12 +++ roles/etcd_common/defaults/main.yml | 3 + roles/etcd_server_certificates/meta/main.yml | 2 +- roles/openshift_etcd_ca/tasks/main.yml | 1 - 11 files changed, 89 insertions(+), 78 deletions(-) create mode 100644 playbooks/byo/openshift-etcd/config.yml delete mode 100644 roles/etcd/files/etcdctl.sh create mode 100644 roles/etcd/templates/etcdctl.sh.j2 delete mode 100644 roles/openshift_etcd_ca/tasks/main.yml diff --git a/playbooks/byo/openshift-etcd/config.yml b/playbooks/byo/openshift-etcd/config.yml new file mode 100644 index 000000000..dd3f47a4d --- /dev/null +++ b/playbooks/byo/openshift-etcd/config.yml @@ -0,0 +1,14 @@ +--- +- include: ../openshift-cluster/initialize_groups.yml + tags: + - always + +- include: ../../common/openshift-cluster/std_include.yml + tags: + - always + +- include: ../../common/openshift-etcd/config.yml + vars: + openshift_cluster_id: "{{ cluster_id | default('default') }}" + openshift_debug_level: "{{ debug_level | default(2) }}" + openshift_deployment_subtype: "{{ deployment_subtype | default(none) }}" diff --git a/roles/etcd/defaults/main.yaml b/roles/etcd/defaults/main.yaml index 29153f4df..e45f53219 100644 --- a/roles/etcd/defaults/main.yaml +++ b/roles/etcd/defaults/main.yaml @@ -13,5 +13,4 @@ etcd_listen_peer_urls: "{{ etcd_peer_url_scheme }}://{{ etcd_ip }}:{{ etcd_peer_ etcd_advertise_client_urls: "{{ etcd_url_scheme }}://{{ etcd_ip }}:{{ etcd_client_port }}" etcd_listen_client_urls: "{{ etcd_url_scheme }}://{{ etcd_ip }}:{{ etcd_client_port }}" -etcd_data_dir: /var/lib/etcd/ etcd_systemd_dir: "/etc/systemd/system/{{ etcd_service }}.service.d" diff --git a/roles/etcd/files/etcdctl.sh b/roles/etcd/files/etcdctl.sh deleted file mode 100644 index 0e324a8a9..000000000 --- a/roles/etcd/files/etcdctl.sh +++ /dev/null @@ -1,11 +0,0 @@ -#!/bin/bash -# Sets up handy aliases for etcd, need etcdctl2 and etcdctl3 because -# command flags are different between the two.
