Hi list, I am sending this email in case it's also interesting to someone in the community, and to also avoid it bit rotting in my repo [1]
A few months ago, I started working on bringing up k3s on OpenWrt. I managed to have a small k8s cluster with nodes running centos and openwrt. Likely other linux distros will also do, but I didn't test combination of different architectures yet. K3s is on its own a k8s distribution. It provides a single packaged binary for amd64, arm64, armhf. If I understand it right, the binary is supposed to be as userland-dependency-free as possible, with dependencies only on the kernel. One thing worth noting is that the openwrt package is NOT official, neither from OpenWrt nor k3s upstream project. It packages binary executables distributed by k3s upstream project which is generally frowned upon if sources are available. The other thing is that k3s (or k8s) requires quite a few kernel features to run, some of them only available as builtin (compared to kmod). This means you will likely to build your own image to use it. The required features as of k3s 1.0.0 are recorded as well and available as a default off config symbol CONFIG_k3s_KERNEL [2] [1] https://github.com/yousong/waller/tree/master/k3s [2] https://github.com/yousong/waller/blob/c3ee00451ce12e869277bbd73b08652882c52010/k3s/Makefile#L69-L79 Happy hacking, yousong _______________________________________________ openwrt-devel mailing list openwrt-devel@lists.openwrt.org https://lists.openwrt.org/mailman/listinfo/openwrt-devel
