docker run -it --rm joseluisq/alpine-mysql-client mysql --version
# mysql  Ver 15.1 Distrib 10.6.4-MariaDB, for Linux (x86_64) using readline 5.1

• Default user (unprivileged) is mysql.
• mysql home directory is located at /home/mysql.
• If you want a fully privileged user try root. E.g. append a --user root argument to docker run.

This image comes with some additional tools.

mysql_exporter is a custom tool that exports a database script using mysqldump. Additionally, it supports gzip compression. It can be configured via environment variables or using .env file.

# Connection settings (optional)
DB_PROTOCOL=tcp
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DEFAULT_CHARACTER_SET=utf8

# GZip export file (optional)
DB_EXPORT_GZIP=false

# SQL or Gzip export file (optional).
# If `DB_IMPORT_GZIP` is `true` then file name should be `database_name.sql.gz`
DB_EXPORT_FILE_PATH=database_name.sql

# Database settings (required)
DB_NAME=""
DB_USERNAME=""
DB_PASSWORD=""

# Additional arguments (optional)
DB_ARGS=

Notes:

• DB_EXPORT_GZIP=true: Compress the SQL file using Gzip (optional). If false or not defined then the exported file will be a .sql file.
• DB_ARGS: can be used to pass more mysqldump arguments (optional).
• A .env example file can be found at ./mysql_exporter.env

The following Docker commands create a container to export a database and then remove such container automatically.

Note: mysql_exporter supports environment variables or a .env file passed as an argument.

docker run --rm -it \
    --user $(id -u $USER):$(id -g $USER) \
    --volume $PWD:/home/mysql/sample \
    --workdir /home/mysql/sample \
        joseluisq/alpine-mysql-client:1 \
        mysql_exporter production.env

# Alpine / MySQL Client - Exporter
# ================================
# mysqldump  Ver 10.17 Distrib 10.4.12-MariaDB, for Linux (x86_64)
# Exporting database `mydb` into a SQL script file...
# Output file: mydb.sql.gz (SQL GZipped)
# Database `mydb` was exported on 0s successfully!
# File exported: mydb.sql.gz (10M / SQL GZipped)

Notes:

• --volume $PWD:/home/mysql/sample specificy a bind mount directory from host to container.
• $PWD is just my host working directory. Use your own path.
• /home/mysql/ is the default home directory user (optional). View User privileges section above.
• /home/mysql/sample is a container directory that Docker will create for us.
• --workdir /home/mysql/sample specificies the working directory used by default inside the container.
• production.env is a custom env file path with the corresponding environment variables passed as argument. That file shoud available in your host working directory. E.g $PWD in my case.

version: "3.3"

services:
  exporter:
    image: joseluisq/alpine-mysql-client:1
    env_file: .env
    command: mysql_exporter
    working_dir: /home/mysql/sample
    volumes:
      - ./:/home/mysql/sample
    networks:
      - default

mysql_importer is a custom tool that imports a SQL script file (text or Gzip) using mysql command. It can be configured via environment variables or using .env file.

# Connection settings (optional)
DB_PROTOCOL=tcp
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DEFAULT_CHARACTER_SET=utf8

# GZip import support (optional)
DB_IMPORT_GZIP=false

# SQL or Gzip import file (required)
# If `DB_IMPORT_GZIP` is `true` then file name should be `database_name.sql.gz`
DB_IMPORT_FILE_PATH=database_name.sql

# Database settings (required)
DB_NAME=""
DB_USERNAME=""
DB_PASSWORD=""

# Additional arguments (optional)
DB_ARGS=

The following Docker commands create a container to import an SQL script file to a specific database and remove the container afterward.

Note: mysql_importer supports environment variables or a .env file passed as an argument.

docker run --rm -it \
    --user $(id -u $USER):$(id -g $USER) \
    --volume $PWD:/home/mysql/sample \
    --workdir /home/mysql/sample \
        joseluisq/alpine-mysql-client:1 \
        mysql_importer production.env
