运行多个Docker将文件组合在一起
multidocker的Python项目详细描述
多码头
将多个撰写文件作为一个运行。
为什么？什么时候？怎样？什么？
我使用一个反向代理容器使几个容器可以通过https访问。 因此，容器需要在同一个合成文件中。 过了一段时间，文件开始失控，所以我编写了这个工具，使其更易于管理。
设置
0个。要求
dockerdocker-composepython 3.6+
一。安装MultiDocker
$ pip3 install multidocker
2.设置目录
您需要以下设置：
$ tree
multidocker/
├── some_app/
│ └── docker-compose.yml
└── other_app/
└── docker-compose.yml
示例
$ tree
multidocker/
├── nextcloud/
│ └── docker-compose.yml
└── proxy/
├── docker-compose.yml
├── htpasswd
├── nginx-extra-options.conf
└── vhost.d/
nextcloud/docker-compose.yml：
---
version: '3.6'
# these two containers share the nextcloud
# network over which they will communicate
services:
nextcloud:
restart: unless-stopped
image: nextcloud
environment:
VIRTUAL_HOST: "my_hostname.example.com"
VIRTUAL_PORT: 80
LETSENCRYPT_HOST: "my_hostname.example.com"
volumes:
- nextcloud_data:/var/www/html:rw
# this adds the 'multidocker' network that allows
# communication between compose files
external: true
networks:
- nextcloud
depends_on:
- nextcloud_db
nextcloud_db:
restart: unless-stopped
image: postgres:10.4
environment:
POSTGRES_PASSWORD: "secret"
POSTGRES_USER: "nextcloud"
volumes:
- nextcloud_db:/var/lib/postgresql/data:rw
networks:
- nextcloud
...
proxy/docker-compose.yml：
---
version: '3.6'
services:
nginx:
image: jwilder/nginx-proxy:alpine
ports:
- "80:80"
- "443:443"
volumes:
- nginx_conf:/etc/nginx/conf.d:rw
- ./nginx-extra-options.conf:/etc/nginx/conf.d/extra.conf:ro
- ./htpasswd:/etc/nginx/htpasswd_default:ro
- ./vhost.d:/etc/nginx/vhost.d:ro
- nginx_html:/usr/share/nginx/html:ro
- nginx_dhparam:/etc/nginx/dhparam:rw
- certificates:/etc/nginx/certs:ro
- /var/run/docker.sock:/tmp/docker.sock:ro
# this adds the 'multidocker' network that allows
# communication between compose files
external: true
labels:
- "com.github.jrcs.letsencrypt_nginx_proxy_companion.nginx_proxy"
letsencrypt:
image: jrcs/letsencrypt-nginx-proxy-companion
volumes:
- nginx_conf:/etc/nginx/conf.d:rw
- nginx_vhost:/etc/nginx/vhost.d:rw
- nginx_html:/usr/share/nginx/html:rw
- certificates:/etc/nginx/certs:rw
- /var/run/docker.sock:/var/run/docker.sock:ro
depends_on:
- nginx

用法
您可以使用所有的docker-compose命令：ps、up、down、logs等。
一次性使用
$ multidocker up -d Creating network "multidocker_nextcloud_nextcloud" with the default driver Creating network "multidocker_multidocker" with the default driver Creating volume "multidocker_nextcloud_nextcloud_data" with default driver Creating volume "multidocker_nextcloud_nextcloud_db" with default driver Creating volume "multidocker_proxy_certificates" with default driver Creating volume "multidocker_proxy_nginx_conf" with default driver Creating volume "multidocker_proxy_nginx_dhparam" with default driver Creating volume "multidocker_proxy_nginx_html" with default driver Creating nextcloud_nextcloud_db ... done Creating proxy_nginx ... done Creating nextcloud_nextcloud ... done
交互模式
我还添加了一个交互模式。您可以在不带任何参数的情况下运行multidocker来启动它：
$ multidocker
Interactive Mode
You can run docker subcommands here, like so:
------------------------------------------
| multidocker> ps || Name Command State Ports || ---------------------------------------|| container_name /init Up || multidocker> |
------------------------------------------
Commands:
build Build or rebuild services
bundle Generate a Docker bundle from the Compose file
config Validate and view the Compose file
create Create services
down Stop and remove containers, networks, images, and volumes
events Receive real time events from containers
exec Execute a command in a running container
help Get help on a command
images List images
kill Kill containers
logs View output from containers
pause Pause services
port Print the public port for a port binding
ps List containers
pull Pull service images
push Push service images
restart Restart services
rm Remove stopped containers
run Run a one-off command
scale Set number of containers for a service
start Start services
stop Stop services
top Display the running processes
unpause Unpause services
up Create and start containers
version Show the Docker-Compose version information
Multidocker Commands:
cat Output combined compose file to disk
help Show this help text
reload Reload the compose files from disk
write Write the combined compsose file to disk
quit, exit Exit interactive mode (ctrl+d also works)您可以在这个提示下运行所有docker compose命令。它省去了在每个命令前键入multidocker的麻烦。
它还节省了时间，因为它将组合的合成文件保存在内存中。如果更改了一个撰写文件，则应运行reload命令。
改进：
- []文件更改时自动重新加载
- []在交互模式下使用readline
- []交互式模式下的外壳式历史记录
- []升级到python 3.7以使用改进的
subprocess.run - []检查示例是否实际有效
