cubrid

Start Containers for Broker and DB Server

#Start a Server instance as follows:
docker run -d -e 'CUBRID_COMPONENTS=SERVER' --name server-container-name cubrid:tag

#And Start a Broker instance as follows:
docker run -d -e 'CUBRID_COMPONENTS=BROKER' -e 'CUBRID_DB_HOST=cubrid_server' -e 'CUBRID_DB=dbname' --name broker-container-name --link cubrid_server:server-container-name cubrid:tag

#Create a isolated network for HA
docker network create --driver bridge cubrid_ha_net

#Start a Master instance (with Broker) as follows:
docker run -d --net=cubrid_ha_net -e 'CUBRID_COMPONENTS=HA' -e 'CUBRID_DB_HOST=master:slave' -e 'CUBRID_DATABASE=db' --hostname master --name master cubridkr/cubrid:10.2.0.8797

#Start a Slave instance (with Broker) as follows:
docker run -d --net=cubrid_ha_net -e 'CUBRID_COMPONENTS=HA' -e 'CUBRID_DB_HOST=master:slave' -e 'CUBRID_DATABASE=db' --hostname slave --name slave cubridkr/cubrid:10.2.0.8797

#The following command runs a cubrid command inside an existing master container instance:
docker exec -it master

# CUBRID HA 상태 확인(각 노드)

[master]$ cubrid changemode db@localhost
The server 'db@localhost''s current HA running mode is active.
[slave]$ cubrid changemode db@localhost
The server 'db@localhost''s current HA running mode is standby.
