Docker killing 3306 usage 端口导致崩溃docker

Question

我正在使用 MaxOs，在安装 Docker 之后，我尝试安装 LaraDock、运行这个命令，它在 LaraDoc 文档中：

laradock % docker-compose up -d nginx mariadb phpmyadmin redis workspace

return 这个错误：

laradock_mariadb_1 is up-to-date
laradock_docker-in-docker_1 is up-to-date
laradock_redis_1 is up-to-date
Starting laradock_mysql_1 ...

当我尝试终止 3306 导致崩溃的 Docker 应用程序时

sudo kill `sudo lsof -t -i:3306`

LaraDock配置：

...
ports:
        - "${MYSQL_PORT}:3306"
...
ports:
        - "${MARIADB_PORT}:3306"

Answer 1

您应该保证 MYSQL_PORT 和 MARIADB_PORT 具有不同的值，否则 Docker 将尝试在主机网络上为两者分配相同的端口。

除此之外，当您不“发布”任何端口时，Docker 上的容器可以运行使用自己的端口，就像很多容器运行端口 80，因为默认情况下，每个容器都有一个网络接口。

注意缩进，总是使用 spaces 而不是 tabs:

...
version: '3.0'

services:
  mysql:
    image: mysql:5.7
    ports:
    - "3306:3306"
  mariadb:
    image: mariadb:10.4
    ports:
    - "3307:3306"
