fix firewall conflict issues with co-located etcd and openshift hosts - added os_firewall dependency to etcd role - updated etcd template to better handle clustered and non-clustered installs - added etcd_ca role - generates a self-signed cert to manage etcd certificates, since etcd peer certificates are required to be client and server certs and the openshift ca will only generate client or server certs (not one authorized for both). - renamed openshift_etcd_certs role to etcd_certificates and updated it to manage certificates generated from the CA managed by the etcd_ca role - remove hard coded etcd_port in openshift_facts - updates for the openshift-etcd common playbook - removed etcd and openshift-etcd playbooks from the byo playbooks directory - added a common playbook for setting etcd launch facts - added an openshift-etcd common service playbook - removed unused variables - fixed tests for embedded_{etcd,dns,kube} in openshift_master - removed old workaround for reloading systemd units --- roles/etcd/templates/etcd.conf.j2 | 16 +++++++++++----- 1 file changed, 11 insertions(+), 5 deletions(-) (limited to 'roles/etcd/templates/etcd.conf.j2') diff --git a/roles/etcd/templates/etcd.conf.j2 b/roles/etcd/templates/etcd.conf.j2 index 5723b5089..801be2c97 100644 --- a/roles/etcd/templates/etcd.conf.j2 +++ b/roles/etcd/templates/etcd.conf.j2 @@ -8,31 +8,37 @@ {% endfor -%} {% endmacro -%} +{% if groups[etcd_peers_group] and groups[etcd_peers_group] | length > 1 %} ETCD_NAME={{ inventory_hostname }} +ETCD_LISTEN_PEER_URLS={{ etcd_listen_peer_urls }} +{% else %} +ETCD_NAME=default +{% endif %} ETCD_DATA_DIR={{ etcd_data_dir }} #ETCD_SNAPSHOT_COUNTER="10000" #ETCD_HEARTBEAT_INTERVAL="100" #ETCD_ELECTION_TIMEOUT="1000" -ETCD_LISTEN_PEER_URLS={{ etcd_listen_peer_urls }} ETCD_LISTEN_CLIENT_URLS={{ etcd_listen_client_urls }} #ETCD_MAX_SNAPSHOTS="5" #ETCD_MAX_WALS="5" #ETCD_CORS="" -# + +{% if groups[etcd_peers_group] and groups[etcd_peers_group] | length > 1 %} #[cluster] ETCD_INITIAL_ADVERTISE_PEER_URLS={{ etcd_initial_advertise_peer_urls }} ETCD_INITIAL_CLUSTER={{ initial_cluster() }} ETCD_INITIAL_CLUSTER_STATE={{ etcd_initial_cluster_state }} ETCD_INITIAL_CLUSTER_TOKEN={{ etcd_initial_cluster_token }} -ETCD_ADVERTISE_CLIENT_URLS={{ etcd_advertise_client_urls }} #ETCD_DISCOVERY="" #ETCD_DISCOVERY_SRV="" #ETCD_DISCOVERY_FALLBACK="proxy" #ETCD_DISCOVERY_PROXY="" -# +{% endif %} +ETCD_ADVERTISE_CLIENT_URLS={{ etcd_advertise_client_urls }} + #[proxy] #ETCD_PROXY="off" -# + #[security] {% if etcd_url_scheme == 'https' -%} ETCD_CA_FILE={{ etcd_ca_file }} -- cgit v1.2.3 From ad6a70ebdb5bfd0fad4609b57ace2d27be301cc3 Mon Sep 17 00:00:00 2001 From: Scott Dodson Date: Wed, 5 Aug 2015 16:41:30 -0400 Subject: Reduce heartbeat frequency to 500ms to reduce etcd cpu load Per https://github.com/coreos/etcd/pull/3097 reduce heartbeat to 500ms until we can ensure etcd 2.1 is in use Reduces the impact of but doesn't fix BZ1250310 --- roles/etcd/templates/etcd.conf.j2 | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'roles/etcd/templates/etcd.conf.j2') diff --git a/roles/etcd/templates/etcd.conf.j2 b/roles/etcd/templates/etcd.conf.j2 index 801be2c97..9ac23b1dd 100644 --- a/roles/etcd/templates/etcd.conf.j2 +++ b/roles/etcd/templates/etcd.conf.j2 @@ -16,8 +16,8 @@ ETCD_NAME=default {% endif %} ETCD_DATA_DIR={{ etcd_data_dir }} #ETCD_SNAPSHOT_COUNTER="10000" -#ETCD_HEARTBEAT_INTERVAL="100" -#ETCD_ELECTION_TIMEOUT="1000" +ETCD_HEARTBEAT_INTERVAL="500" +ETCD_ELECTION_TIMEOUT="2500" ETCD_LISTEN_CLIENT_URLS={{ etcd_listen_client_urls }} #ETCD_MAX_SNAPSHOTS="5" #ETCD_MAX_WALS="5" -- cgit v1.2.3
