cicd环境推mysql问题汇总

最终流程说明：

1. dockerfile:　

FROM founder/mysql:5.7
COPY my.cnf /etc/mysql/conf.d/my.cnf
#ADD 1database.sql /docker-entrypoint-initdb.d/1database.sql

ADD 2pkubaseentity.sql /home/
ADD 3pkubasetriple.sql /home/
COPY start.sh /docker-entrypoint-initdb.d/
RUN chmod a+x /docker-entrypoint-initdb.d/start.sh

#ADD 2wisekg.sql /docker-entrypoint-initdb.d/2wisekg.sql

2. start.sh

#!/bin/bash
mysql -uroot -p?? -e "CREATE DATABASE wisekg DEFAULT CHARACTER SET utf8mb4 DEFAULT COLLATE utf8mb4_general_ci;"
mysql -uroot -pasdf -e "use wisekg;source /home/2pkubaseentity.sql;"
mysql -uroot -pagad -e "use wisekg;source /home/3pkubasetriple.sql;"

3. docker-compose

version: '2'

services:
  db:
    image: founder/nlpmysql:${DOCKER_TAG}
    restart: always
    environment:
      MYSQL_ROOT_PASSWORD:
      MYSQL_DATABASE:
      MYSQL_USER:
      MYSQL_PASSWORD:
      MYSQL_ALLOW_EMPTY_PASSWORD:
    ports:
      - '3306:3306'
    labels:
      io.rancher.container.hostname_override: 'container_name'
      io.rancher.scheduler.affinity:host_label: aimysql=true
    volumes:
      - nlp_mysql_data:/var/lib/mysql

volumes:
  nlp_mysql_data:
    driver: ${VOLUME_DRIVER}

4. rancher-compose:

version: '2'

catalog:
  name: Mysql
  version: 5.7.0

      interval: 2000
      strategy: recreate
      initializing_timeout: 6000000
      reinitializing_timeout: 6000000

5. my.cnf

问题汇总;

1.

 不能把start.sh运行，放到initdb下让他自己运行。

2. 每次重新部署的时候，一定要把之前栈里的服务给删掉，要不然重新部署的时候start.sh不生效。（流程见第3点）

 

3. 为什么数据不全。

当设置初始化时间6000s时候，发现服务启动成功，但是初始化数据不全。

其实他的流程是这样的：  先初始化mysql,和数据，6000s过后，数据没加载全，那么重新初始化，结果第二次初始化的时候db这个服务名是存在的，所以就没有进行start.sh。导致直接启动了mysql。然后正常running，导致了我们所现在看到了running但是数据不全的场景。
