Download this Container Image

Usage

To get started with Percona Server for MySQL promptly, this Quickstart guide emphasizes using Docker or installing with APT or YUM. Also you can follow along the Quickstart guide on the Percona website for more details.

Docker

Starting a Detached Container

Start a container with the --detached or -d option to run it in the background. In detached mode, the container exits when the main process used to run it exits.

Start a container named ps with the latest version of Percona Server for MySQL 8.3. This example sets the root password to root (not secure).

$ docker run -d \
  --name ps \
  -e MYSQL_ROOT_PASSWORD=root \
  cgr.dev/chainguard/percona-server:latest

By default, Docker pulls the image from Docker Hub if it is not available locally.

To view the container’s logs, use:

$ docker logs ps --follow

<details> <summary>Expected Output:</summary>

You can access the server when you see the "ready for connections" message in the log.

You can pass options with the docker run command. Example: Set UTF-8 as the default character set and collation for all databases.

$ docker run -d \
  --name ps \
  -e MYSQL_ROOT_PASSWORD=root \
  cgr.dev/chainguard/percona-server:latest \
  --character-set-server=utf8 \
  --collation-server=utf8_general_ci

Accessing the Percona Server Container

Use the docker exec command to get a shell inside the container. Example:

$ docker exec -it ps /bin/bash

For troubleshooting, the error log is located in /var/log/ or /var/log/mysql/, typically named error.log or mysqld.log.

View the error log with:

$ more /var/log/mysql/error.log

Accessing the Database

You can access the database using docker exec or the mysql command inside the container’s shell.

$ docker exec -ti ps mysql -uroot -proot

<details> <summary>Expected Output:</summary>

mysql: [Warning] Using a password on the command line interface can be insecure.

You can also use the MySQL command-line client inside the container’s shell to access the database:

$ mysql -uroot -proot

<details> <summary>Expected Output:</summary>

What are Chainguard Containers?

Chainguard Containers are minimal container images that are secure by default.

In many cases, the Chainguard Containers tagged as :latest contain only an open-source application and its runtime dependencies. These minimal container images typically do not contain a shell or package manager. Chainguard Containers are built with Wolfi, our Linux undistro designed to produce container images that meet the requirements of a more secure software supply chain.

The main features of Chainguard Containers include:

• Minimal design, without unnecessary software bloat
• Daily builds to ensure container images are up-to-date with available security patches
• High quality build-time SBOMs attesting to the provenance of all artifacts within the image
• Verifiable signatures provided by Sigstore
• Reproducible builds with Cosign and apko (read more about reproducibility)

For cases where you need container images with shells and package managers to build or debug, most Chainguard Containers come paired with a -dev variant.

Although the -dev container image variants have similar security features as their more minimal versions, they feature additional software that is typically not necessary in production environments. We recommend using multi-stage builds to leverage the -dev variants, copying application artifacts into a final minimal container that offers a reduced attack surface that won’t allow package installations or logins.
