I have an issue with multiple container from sql-exporter.
My docker-compose.yml looks like this:
db1:
image: mariadb:10.6
restart: unless-stopped
expose:
- 3306
ports:
- 3306:3306
environment:
MYSQL_ROOT_PASSWORD: password1
command: --event_scheduler=ON --log-bin --userstat=ON
volumes:
- ./storage/db1:/var/lib/mysql
db2:
image: mariadb:10.6
restart: unless-stopped
command: --log-bin --userstat=ON
ports:
- 3308:3306
expose:
- 3306
environment:
MYSQL_ROOT_PASSWORD: password2
MYSQL_DATABASE: db-schema2
volumes:
- ./storage/db2:/var/lib/mysql
sql-exporter-db1:
image: prom/mysqld-exporter
expose:
- 9104
ports:
- 9104:9104
links:
- db1
environment:
- DATA_SOURCE_NAME=root:password1@(db1:3306)/
command:
--collect.global_status
--collect.info_schema.innodb_metrics
--collect.auto_increment.columns
--collect.info_schema.processlist
--collect.binlog_size
--collect.info_schema.tablestats

sql-exporter-db2:
image: prom/mysqld-exporter
ports:
- 9105:9104
links:
-db2
volumes:
- ./mysql-exporter/.my.cnf:/root/.my.cnf
environment:

command:

--collect.engine_innodb_status
--web.listen-address=0.0.0.0:9105
when i am running docker compose up, the sql-exporter for db1 runs without
problems and delivers all metrices, i need.
but sql-exporter for db2 just logs these error and quites:
ts=2023-05-26T07:09:18.008Z caller=mysqld_exporter.go:277 level=info
msg="Starting mysqld_exporter" version="(version=0.14.0, branch=HEAD,

msg="Error parsing my.cnf" file=/home/.my.cnf err="failed reading ini file:
open /home/.my.cnf: no such file or directory"
i tried different configurations for sql-exporter for db2 like
* mounting a .my.cnf-file
* dont mounting a .my.cnf-file
' DATA_SOURCE_NAME to @(db2:3306)/
' DATA_SOURCE_NAME to @(db2:3308)/
but every time i see only this 3 log lines and then the container exits.
has somebody the same issue and can help me?
