SQL Server AG with 3 Nodes on Docker

---

Environment

• Node1: sqlNode1 1401->1433 1521->5022 (Primary Node)
• Node2: sqlNode1 1402->1433 1522->5022 (Secondary Node)
• Node3: sqlNode1 1403->1433 1523->5022 (Secondary Node)

STEPS

• Prepare the Dockerfile with HA feather Dockerfile

• Build image with Dockerfile just created create_ha_image.sh

• Create docker-compsoe.yml to create 3 nodes docker-compose.yml

• Create the SQL server nodes with the image which with HA feather

  [root@node3 /mnt/sqlha_ag 10:57]# docker-compose up -d
  [root@node3 /mnt/sqlha_ag 10:57]# docker-compose ps

• Create the certs ,master key and logins on each nodes create_cert_all.sh

• Sync all certs to each other sync_all.sh

• Create AG group and Endpoint on Primary Node create_ag_primary.sh

• Two Secondary nodes join AG group join_ag_sec.sh

• Create TestDB and add TestDB to AG create_TAGDB.sh

• Change roles on each node to test change_primary_to_node2.sh
