Class: tripleo::profile::pacemaker::mysql_bundle
Containerized Mysql Pacemaker HA profile for tripleo
Parameters
- mysql_docker_image
-
(Optional) The docker image to use for creating the pacemaker bundle Defaults to undef
- control_port
-
(Optional) The bundle’s pacemaker_remote control port on the host Defaults to 3123
- bootstrap_node
-
(Optional) The hostname of the node responsible for bootstrapping tasks Defaults to hiera(‘mysql_short_bootstrap_node_name’)
- bind_address
-
(Optional) The address that the local mysql instance should bind to. Defaults to $::hostname
- ca_file
-
(Optional) The path to the CA file that will be used for the TLS configuration. It’s only used if internal TLS is enabled. Defaults to undef
- certificate_specs
-
(Optional) The specifications to give to certmonger for the certificate it will create. Note that the certificate nickname must be ‘mysql’ in the case of this service. Example with hiera:
tripleo::profile::base::database::mysql::certificate_specs: hostname: <overcloud controller fqdn> service_certificate: <service certificate path> service_key: <service key path> principal: "mysql/<overcloud controller fqdn>"Defaults to hiera(‘tripleo::profile::base::database::mysql::certificate_specs’, {}).
- enable_internal_tls
-
(Optional) Whether TLS in the internal network is enabled or not. Defaults to hiera(‘enable_internal_tls’, false)
- gmcast_listen_addr
-
(Optional) This variable defines the address on which the node listens to connections from other nodes in the cluster. Defaults to hiera(‘mysql_bind_host’)
- innodb_flush_log_at_trx_commit
-
(Optional) Disk flush behavior for MySQL under Galera. A value of ‘1’ indicates flush to disk per transaction. A value of ‘2’ indicates flush to disk every second, flushing all unflushed transactions in one step. Defaults to hiera(‘innodb_flush_log_at_trx_commit’, ‘1’)
- clustercheck_user
-
(Optional) The name of the clustercheck user. Defaults to ‘clustercheck’
- clustercheck_password
-
(Optional) The password for the clustercheck user. Defaults to hiera(‘mysql_clustercheck_password’)
- cipher_list
-
(Optional) When enable_internal_tls is true, defines the list of allowed ciphers for the mysql server and Galera (including SST). Defaults to ‘!SSLv2:kEECDH:kRSA:kEDH:kPSK:+3DES:!aNULL:!eNULL:!MD5:!EXP:!RC4:!SEED:!IDEA:!DES:!SSLv3:!TLSv1’
- gcomm_cipher
-
(Optional) When enable_internal_tls is true, defines the cipher used by Galera for the gcomm replication traffic. Defaults to ‘AES128-SHA256’
- sst_tls_cipher
-
(Optional) When enable_internal_tls is true, defines the list of ciphers that the socat may use to tunnel SST connections. Deprecated, now socat is configured based on option cipher_list. Defaults to undef
- sst_tls_options
-
(Optional) When enable_internal_tls is true, defines additional parameters to be passed to socat for tunneling SST connections. Defaults to undef
- two_node_mode
-
(Optional) Whether to configure the resource agent in special 2-node cluster mode, to allow recovering from a network partition. Defaults to false
- ipv6
-
(Optional) Whether to deploy MySQL on IPv6 network. Defaults to str2bool(hiera(‘mysql_ipv6’, false))
- mysql_server_options
-
(Optional) Extras options to deploy MySQL. Useful when deploying Galera cluster. Should be an hash. Defaults to hiera(‘tripleo::profile::base::database::mysql::mysql_server_options’, {}
- mysql_auth_ed25519
-
(Optional) Use MariaDB’s ed25519 authentication plugin to authenticate a user when connecting to the server Defaults to hiera(‘mysql_auth_ed25519’, false)
- pcs_tries
-
(Optional) The number of times pcs commands should be retried. Defaults to hiera(‘pcs_tries’, 20)
- step
-
(Optional) The current step in deployment. See tripleo-heat-templates for more details. Defaults to hiera(‘step’)
- container_backend
-
(optional) Container backend to use when creating the bundle Defaults to ‘docker’
- log_driver
-
(optional) Container log driver to use. When set to undef it uses ‘k8s-file’ when container_cli is set to podman and ‘journald’ when it is set to docker. Defaults to undef
- log_file
-
(optional) Container log file to use. Only relevant when log_driver is set to ‘k8s-file’. Defaults to ‘/var/log/containers/stdouts/galera-bundle.log’
- tls_priorities
-
(optional) Sets PCMK_tls_priorities in /etc/sysconfig/pacemaker when set Defaults to hiera(‘tripleo::pacemaker::tls_priorities’, undef)

-
(Optional) Maximum value for open-files-limit Defaults to 16384
