从bash脚本运行“mysql”命令

I have a MariaDB Docker container that I want to access automatically with the help of a bash script.

我有一个MariaDB Docker容器，我希望借助bash脚本自动访问它。

I'm using Docker compose:

我正在使用Docker撰写：

version: '3'
services:
  drupal:
    image: jonasvbogaert/php-docker:${IMAGE_VERSION}
    container_name: drupalenv
    ports:
      - 8080:80
    volumes:
      - /var/www/html/
    restart: always
    environment:
      DRUPAL_SITE_NAME: Drupal
      DRUPAL_USER: admin
      DRUPAL_PASS: admin
  mariadb:
    image: mariadb:latest
    container_name: mariadbenv
    restart: always
    ports:
      - 3036:3036
    depends_on:
      - drupal
    environment:
      MYSQL_ROOT_PASSWORD: ""
      MYSQL_ALLOW_EMPTY_PASSWORD: 'yes'
      MYSQL_USER: drupal
      MYSQL_PASSWORD: drupal
      MYSQL_DATABASE: drupal`

The first command is to dive in the container (works fine):

第一个命令是潜入容器（工作正常）：

docker exec -it mariadbenv bash

But the second one:

但第二个：

mysql

outputs the following error:

输出以下错误：

ERROR 1045 (28000): Access denied for user 'jonasvb'@'localhost' (using password: NO) the input device is not a TTY

ERROR 1045（28000）：用户'jonasvb'@'localhost'拒绝访问（使用密码：NO）输入设备不是TTY

When I enter "mysql" myself, it works.

当我自己输入“mysql”时，它有效。

This is the script I use:

这是我使用的脚本：

function main () {
  getUserInput
}


function fireDocker () {
  if [ $DRUPAL_VERSION = "7" ]; then                            
    IMAGE_VERSION="drupal7"                                     
    export IMAGE_VERSION                                        
    docker-compose up -d                                         
    mountDump
  else
    IMAGE_VERSION="drupal8"                                     
    export IMAGE_VERSION                                        
    docker-compose up -d                                        
    mountDump
  fi
}

function getUserInput () {
  echo "Enter Drupal version (7 or 8)"
  read DRUPAL_VERSION                                           # Read 
  fireDocker $DRUPAL_VERSION
}

function mountDump(){
  docker exec -it mariadbenv bash
  mysql

}


main

When I execute the first command without -t flag. I have this:

当我执行第一个没有-t标志的命令时。我有这个：

And it stays like this.

它就像这样。

You can run mysql commands in container using

您可以使用容器在容器中运行mysql命令

docker exec -i some_mysql_container mysql --user=root --password=root  <<< "select database();"

Here the password and username should match with the one that is being used in the container.

这里的密码和用户名应该与容器中使用的密码和用户名相匹配。

A better approach in your cases would be to place all the dumps in the host and then map that host directory inside container at /docker-entrypoint-initdb.d. For a better understanding how all dumps are imported in container you may look at official entrypoint.sh of mariadb:latest

在您的情况下，更好的方法是将所有转储放在主机中，然后将该主机目录映射到容器中的/docker-entrypoint-initdb.d。为了更好地理解如何在容器中导入所有转储，您可以查看mariadb：latest的官方entrypoint.sh

L170 onwards:

L170起：

    for f in /docker-entrypoint-initdb.d/*; do
        case "$f" in
            *.sh)     echo "$0: running $f"; . "$f" ;;
            *.sql)    echo "$0: running $f"; "${mysql[@]}" < "$f"; echo ;;
            *.sql.gz) echo "$0: running $f"; gunzip -c "$f" | "${mysql[@]}"; echo ;;
            *)        echo "$0: ignoring $f" ;;
        esac
        echo
    done

This enables users to place everything inside /docker-entrypoint-initdb.d/ and then

这使用户可以将所有内容放在/docker-entrypoint-initdb.d/中
