docker（十九）：docker stack部署wordpress应用

1.部署swarm的stack部署wordpress。
2.参考官方文档

https://docs.docker.com/compose/compose-file/

1.docker stack部署帮助命令

[vagrant@swarm-manager wordpress0714]$ docker stack Usage: docker stack [OPTIONS] COMMAND Manage Docker stacks Options: --orchestrator string Orchestrator to use (swarm|kubernetes|all) Commands: deploy Deploy a new stack or update an existing stack ls List stacks ps List the tasks in the stack rm Remove one or more stacks services List the services in the stack Run 'docker stack COMMAND --help' for more information on a command.

2. docker-compose.yml文件

version: '3' services: web: image: hub.c.163.com/library/wordpress ports: - 8080:80 environment: WORDPRESS_DB_HOST: mysql WORDPRESS_DB_PASSWORD: root networks: - my-network depends_on: - mysql deploy: mode:replicated replicas: 3 restart_policy: condition: on-failure delay: 5s max_attempts: 3 update_config: parallelism: 1 delay: 10s mysql: image: hub.c.163.com/library/mysql:5.7 environment: MYSQL_ROOT_PASSWORD: root MYSQL_DATABASE: wordpress volumes: - mysql-data:/var/lib/mysql networks: - my-network deploy: mode: global placement: constraints: - node.role == manager volumes: mysql-data: networks: my-network: driver: overlay

备注：文件格式很重要，每个空格错了都不行。这个文件是成功了的。

[vagrant@swarm-manager wordpress0714]$ docker stack deploy wordpress --compose-file=docker-compose.yml Creating network wordpress_my-network Creating service wordpress_web Creating service wordpress_mysql
