我的yml文件中似乎存在缩进问题.我在这里读了一些其他问题,并尝试了各种缩进方案.我仍然无法让它工作.在发布此问题之前,我故意删除了env名称/ pws.
version: '2'
ghost:
image: ghost:latest
container_name: ghost-blog #Specify a custom container name,rather than a generated default name.
environment:
- NODE_ENV=production
- MysqL_DATABASE=db-name # Change {{db-name}}
- MysqL_USER=user # Change {{username}}
- MysqL_PASSWORD=pass # Change {{db-password}}
# - "MAILGUN_USER={{mailgun-user}}" # Change {{mailgun-user}}
# - "MAILGUN_PASSWORD={{mailgun-password}}" # Change {{mailgun-password}}
volumes:
- ./ghost:/var/lib/ghost # persist the data
ports:
- 2368:2368
depends_on:
- MysqL # ensure that the database will start first
restart: always
MysqL:
image: MysqL:latest
container_name: ghost-db
environment:
- MysqL_DATABASE=dbname # Change {{db-name}}
- MysqL_ROOT_PASSWORD=db-pass # Change {{root-password}}
- MysqL_USER=user # Change {{username}}
- MysqL_PASSWORD=sq-pass # Change {{db-password}}

最佳答案
将来,您可以使用此website来检查它有什么问题,然后随时修复它.
编辑：
所以你的docker-compose文件遇到的问题如下：
>您没有添加服务：版本和之后
>如果您想要最新的图像,则不必传递：latest标记,当您需要特定版本的图像时,您将传递标记,并且在“”之间完成
至于代码,它应该如下：
version: '2'
services:
ghost:
image: ghost
container_name: ghost-blog
environment:
- NODE_ENV=production
- MysqL_DATABASE=db-name
- MysqL_USER=user
- MysqL_PASSWORD=pass
# - "MAILGUN_USER={{mailgun-user}}"
# - "MAILGUN_PASSWORD={{mailgun-password}}" # Change {{mailgun-password}}
volumes:
- ./ghost:/var/lib/ghost # persist the data
ports:
- 2368:2368
depends_on:
- MysqL # ensure that the database will always start first
restart: always
MysqL:
image: MysqL
container_name: ghost-db
environment:
- MysqL_DATABASE=dbname # Change {{db-name}}
- MysqL_ROOT_PASSWORD=db-pass # Change {{root-password}}
- MysqL_USER=user # Change {{username}}
- MysqL_PASSWORD=sq-pass # Change {{db-password}}
volumes:
- ./db:/var/lib/MysqL
restart: always
