docker - 为什么docker容器名称末尾有一个随机数？

Question

我有一个 docker-compose.yml 文件，如下(其中一部分):

version: '3.5'
services:
    framework:
    image: ${DOCKER_REGISTRY}/gme/fmk:${COMPOSE_PROJECT_NAME}
    build: ./fmk
    ports:
      - "2020:2020"
      - "2025:2025"
      - "4999:4999"
    volumes:
      - ${FOLDER_ENV}/workspace/logs/framework:/var/log/gcti
      - ${FOLDER_ENV}/..:/usr/local/genesys/gsg_qaart

我得到的是:

vagrant@docker:/repos/gsg_qaart/docker$ docker-compose ps
]              Name                             Command               State                                             
Ports
-----------------------------------------------------------------------------------------------------------------------------------------------------------------------
callback_framework_1_df361f67842c   /bootstrap.sh                    Up      0.0.0.0:2020->2020/tcp, 0.0.0.0:2025->2025/tcp, 0.0.0.0:4999->4999/tcp, 5432/tcp

正如你所看到的，这个名字很奇怪，它应该是“callback_framwork_1”，为什么最后有一个随机数？

顺便说一句，我正在使用:

vagrant@docker:/repos/gsg_qaart/docker$ docker -v
Docker version 18.09.0, build 4d60db4
vagrant@docker:/repos/gsg_qaart/docker$ docker-compose -v
docker-compose version 1.23.1, build b02f1306

谢谢。

编辑。

此更改已在 v1.23.2 中恢复

<小时/>

所以 compose v1.23 有一个重要的变化，https://github.com/docker/compose/releases/tag/1.23.0

The default naming scheme for containers created by Compose in this version has changed from project_service_index to project_service_index_slug, where slug is a randomly-generated hexadecimal string. Please make sure to update scripts relying on the old naming scheme accordingly before upgrading.

因此，如果您想要一个确定的容器名称，请使用

services:
    framework:
        container_name: framework
