Brad Davidson	c02dceb7ad	Make rootless settings configurable ... Add enivironment variables for port-driver, cidr, mtu, and disable-host-loopback settings. Since rootless is still experimental, I don't think they deserve full CLI flag status. Signed-off-by: Brad Davidson <brad.davidson@rancher.com>	2 years ago

Dirk Müller	fa0fa8b1d0	Update golangci-lint to 1.45.2 ... This requires a further set of gofmt -s improvements to the code, but nothing major. golangci-lint 1.45.2 brings golang 1.18 support which might be needed in the future. Signed-off-by: Dirk Müller <dirk@dmllr.de>	3 years ago

Akihiro Suda	e672c988e4	rootless: allow kernel.dmesg_restrict=1 ... When `/dev/kmsg` is unreadable due to sysctl value `kernel.dmesg_restrict=1`, bind-mount `/dev/null` into `/dev/kmsg` Fix issue 3011 Signed-off-by: Akihiro Suda <akihiro.suda.cz@hco.ntt.co.jp>	4 years ago
Akihiro Suda	6e8284e3d4	rootless: enable resource limitation (requires cgroup v2, systemd) ... Now rootless mode can be used with cgroup v2 resource limitations. A pod is executed in a cgroup like "/user.slice/user-1001.slice/user@1001.service/k3s-rootless.service/kubepods/podd0eb6921-c81a-4214-b36c-d3b9bb212fac/63b5a253a1fd4627da16bfce9bec58d72144cf30fe833e0ca9a6d60ebf837475". This is accomplished by running `kubelet` in a cgroup namespace, and enabling `cgroupfs` driver for the cgroup hierarchy delegated by systemd. To enable cgroup v2 resource limitation, `k3s server --rootless` needs to be launched as `systemctl --user` service. Please see the comment lines in `k3s-rootless.service` for the usage. Running `k3s server --rootless` via a terminal is not supported. When it really needs to be launched via a terminal, `systemd-run --user -p Delegate --tty` needs to be prepended to create a systemd scope.
