docker-mysql-via-http

An Alpine-based Docker image for downloading a file and executing it with the mysql client.

There are tags for Alpine 3.20, 3.19, 3.18, and 3.17. This image is available on both the linux/amd64 and linux/arm64 platforms.

# The "latest" tag will always point to the most recent version of Alpine.
# Assuming 3.20.2 is most recent, these three commands all pull the same image.
docker pull @mindgrub/mysql-via-http:latest
docker pull @mindgrub/mysql-via-http:1-alpine-3.20
docker pull @mindgrub/mysql-via-http:1-alpine-3.20.2

# Pull other versions or architectures.
docker pull --platform linux/arm64 @mindgrub/mysql-via-http:1-alpine-3.18

Environment Variables

  • SQL_FILE_URL – Required. The URL of the .sql or .sql.gz to ingest.
  • DB_HOST – Required. The hostname to which mysql will connect.
