Have you ever seen the “exec /docker-entrypoint.sh: exec format error” error message on your server while running any docker image or Kubernetes pods? This is most probably because you are running some other CPU architecture container image on your server, or did you ever use --platform linux/x86_64 option on your Apple silicon M1, M2 MacBook? If yes, then you are not getting the native performance of Apple silicon, and it may be draining your MacBook battery. To avoid this kind of error and performance issue, we need to run the correct multi-arch container image, or we may need to build our own image because all container public image does not have the multi-arch image available.

In this blog post, we will learn what are multi-arch container images. How does it work? How to build and promote them? and we will write a sample code for building a multi-arch image in the CI/CD pipeline.

Before understanding DevSecOps, let’s understand what DevOps is. DevOps is the combination of cultural philosophies, practices, and tools that increase an organization’s ability to deliver applications and services at high velocity.

In fast-moving projects, security often lags behind and is given low priority, which may lead to buggy code and hacks. Let’s see how we can reduce the risk of attack by integrating security into our DevOps pipeline.
