OSTree

What hackers pick instead

• Flux CDKubernetes GitOps tool that syncs clusters from git, including image tag updates and Helm releases. One critic calls it large and clunky next to Argo CD.44recommend
• DokkuLets people run Docker apps on their own cheap server with little devops work, though critics note a steep learning curve from its CLI.22recommend
• KamalFree tool for deploying Docker containers to your own servers with no-downtime deploys. Most common caveat: the build and config setup, including secrets, takes time to get running.21recommend
• Argo CDPeople recommend Argo CD as a GitOps tool that syncs Kubernetes manifests from Git and shows what is deployed. Critics mainly point to awkward Helm and YAML layering.21recommend
• bootcPeople recommend bootc for building and deploying Linux system images as OCI containers, with simpler composition and recoverable upgrades. Common caveat: OCI tarball layers are a poor fit.16recommend
