KubeFM recently invited me to talk about my project "barco: Linux Containers From Scratch in C". In this episode, I talk about why Linux containers don't exist, how to use cgroups and namespaces to isolate a process, how to secure the container with seccomp and capabilities, and how to make the right syscall from C to build your own container engine. Thank you, KubeFM, for having me!
OpenID Connect (OIDC) is an authentication protocol that extends OAuth 2.0, providing a solid and standardized method for authentication often involving an ID token in the JWT (JSON Web Token) format. OIDC is the recommended way to authenticate with GitHub Enterprise Server when setting up GitHub Actions. Since the setup can be tricky, I've created a Terraform configuration that makes it easier to get started.
