解決方案
#建立在scripts目錄下mysqld啟動腳本
#!/bin/bash # From https://github.com/docker-library/mysql/issues/99 set -e # fail on any error echo '* Working around permission errors in Docker on Mac locally by making sure that "mysql" uses the same uid and gid as the host volume' TARGET_UID=$(stat -c "%u" /var/lib/mysql) echo '-- Setting mysql user to use uid '$TARGET_UID usermod -o -u $TARGET_UID mysql || true TARGET_GID=$(stat -c "%g" /var/lib/mysql) echo '-- Setting mysql group to use gid '$TARGET_GID groupmod -o -g $TARGET_GID mysql || true echo echo '* Starting MySQL' chown -R mysql:root /var/run/mysqld/ /entrypoint.sh mysqld --user=mysql --console

建立docker-compose.py，指定run-mysqld.sh腳本為容器入口
test-mysql: image: mysql ports: - "3306:3306" volumes: - /localhost/mysql/data:/var/lib/mysql - ./scripts/run-mysqld.sh:/run-mysqld.sh environment: - MYSQL_DATABASE=play - MYSQL_USER=play - MYSQL_PASSWORD=play - MYSQL_ROOT_PASSWORD=123456 entrypoint: /run-mysqld.sh
登入後複製
- ##執行docker-compose up指令，啟動容器
