创建namespace
kubectl create ns mattermost
创建两个PV存储数据
新建mattermost-data用于存储数据，mattermost-plugins用户存储插件。

创建数据库
准备一个PG数据库，然后添加账号。
postgres=# CREATE DATABASE mattermost;
CREATE DATABASE
postgres=# CREATE USER mmuser WITH PASSWORD 'mmuser-password';
CREATE ROLE
postgres=# GRANT ALL PRIVILEGES ON DATABASE mattermost to mmuser;
GRANT
postgres=# \q
could not save history to file "/var/lib/pgsql/.psql_history": No such file or directory
[postgres@zeyang-nuc-service ~]$ exit
logout
自定义value.yml

连接外部数据库
mysql示例：
## If use this please disable the mysql chart by setting mysql.enable to false
externalDB:
enabled: true
## postgres or mysql
externalDriverType: "mysql"
## postgres: "postgres://<USERNAME>:<PASSWORD>@<HOST>:5432/<DATABASE_NAME>?sslmode=disable&connect_timeout=10"
## mysql: "<USERNAME>:<PASSWORD>@tcp(<HOST>:3306)/<DATABASE_NAME>?charset=utf8mb4,utf8&readTimeout=30s&writeTimeout=30s"
externalConnectionString: "xxxx:xxxxx@tcp(xxxx:3306)/mattermost?charset=utf8mb4,utf8\u0026readTimeout=30s\u0026writeTimeout=30s"
postgres示例:（这是我们使用的）
## If use this please disable the mysql chart by setting mysql.enable to false
externalDB:
enabled: true
## postgres or mysql
externalDriverType: "postgres"
## postgres: "postgres://<USERNAME>:<PASSWORD>@<HOST>:5432/<DATABASE_NAME>?sslmode=disable&connect_timeout=10"
## mysql: "<USERNAME>:<PASSWORD>@tcp(<HOST>:3306)/<DATABASE_NAME>?charset=utf8mb4,utf8&readTimeout=30s&writeTimeout=30s"
externalConnectionString: "postgres://mmuser:mmuser-password@192.168.1.200:5432/mattermost?sslmode=disable&connect_timeout=10"
验证数据库可以正常访问
psql -h 192.168.1.200 -p 5432 -d mattermost -U mmuser
部署
helm install mattermost-server --namespace mattermost ./mattermost-team-edition
helm delete mattermost-server --namespace mattermost ./mattermost-team-edition
FAQ
err=pq: no pg_hba.conf entry for host \"10.244.0.148\", user \"mmuser\", database \"mattermost\", SSL off"}
修改pg_hba.conf、 postgres.conf
## pg_hba.conf
host all all 192.168.1.0/24 md5
host all all 10.244.0.1/24 md5
## postgres.conf
