Running WordPress on Containers
- WordPress continues to be one of the most popular content management systems in the world and containers offer several significant benefits for WordPress environments by enhancing security, scalability, and portability.
- For long-time WordPress administrators, creating a container-based LEMP environment locally using Docker Compose can be a good starting point for migrating from bare metal servers or VPSs to containerized environments.
- When choosing a base container image for WordPress environments, it is important to consider factors such as the image provider, features and ease of use, update frequency and patching, size and attack surface, and the number of vulnerabilities.
- CVEs, or Common Vulnerabilities and Exposures, are publicly known security flaws that can be exploited by malicious actors to gain unauthorized access, steal data, or disrupt systems.
- Grype is a popular open-source CVE scanner that scans for known vulnerabilities in container images and filesystems, helping to make an informed choice when deciding on which base image to use for WordPress environments.
- Results show that some popular WordPress container images are riddled with vulnerabilities, making it critical to choose base images wisely.
- Chainguard will host a free online event on 24th September where participants can learn more about the Chainguard WordPress image.
- Chainguard Academy offers documentation and tutorials about software supply chain security, container image security, Wolfi, and Chaiguard Images for those interested in learning more about Chainguard Images and Wolfi.
- Running WordPress on containerized environments can be beneficial for enhanced security, scalability, and portability, but it is important to choose base container images wisely to avoid vulnerabilities.
