[linkerd] where to pass the flag `--set proxyInit.runAsRoot=true`?
Hello,
The pre-checks say: "There are nodes using the docker container runtime and proxy-init container must run as root user. Try installing linkerd via --set proxyInit.runAsRoot=true"
But when I run the install script with:
curl -sL run.linkerd.io/install > linkerd-install.sh sudo ./linkerd-install.sh --set proxyInit.runAsRoot=true
the same happens.
Maybe it takes to install Linkerd on the cloud? My cluster runs in virt-manager with 2 nodes

On a fresh install with containerd in qemu/kvm, it goes well

Hi @thomas.bucaioni,
The calico network plugin is responsible for setting up one or multiple IP pools for the pods running in the Kubernetes cluster. By default, all nodes host subnets of a given pool, but node selectors can be used to isolate a specific pool to a desired subset of nodes of the cluster.
https://projectcalico.docs.tigera.io/getting-started/kubernetes/hardway/configure-ip-pools

hi @thomas.bucaioni this flag will be passed in linkerd install command. skip the check --pre command and directly installed the linkerd with this flag.
linkerd install --set proxyInit.runAsRoot=true | kubectl apply -f -

Same on aws:
ubuntu@cpnode:~$ curl -sL run.linkerd.io/install | sh Downloading linkerd2-cli-stable-2.11.2-linux-amd64... % Total % Received % Xferd Average Speed Time Time Time Current Dload Upload Total Spent Left Speed 0 0 0 0 0 0 0 0 --:--:-- --:--:-- --:--:-- 0 100 44.7M 100 44.7M 0 0 6348k 0 0:00:07 0:00:07 --:--:-- 7091k Download complete! Validating checksum... Checksum valid. Linkerd stable-2.11.2 was successfully installed 🎉 Add the linkerd CLI to your path with: export PATH=$PATH:/home/ubuntu/.linkerd2/bin Now run: linkerd check --pre # validate that Linkerd can be installed linkerd install | kubectl apply -f - # install the control plane into the 'linkerd' namespace linkerd check # validate everything worked! linkerd dashboard # launch the dashboard Looking for more? Visit https://linkerd.io/2/tasks ubuntu@cpnode:~$ export PATH=$PATH:/home/ubuntu/.linkerd2/bin ubuntu@cpnode:~$ linkerd check --pre there are nodes using the docker container runtime and proxy-init container must run as root user. try installing linkerd via --set proxyInit.runAsRoot=true
But a simple service exposed doesn't seem to work neither...

Now I get:
‼ cluster networks can be verified the following nodes do not expose a podCIDR: wnode see https://linkerd.io/2.11/checks/#l5d-cluster-networks-verified for hints
but since only calico sets the pod Cidr, the worker node can't expose one?

Hi @chrispokorni
Of course, calico have more options than just setting a Cidr. Thank you for the link0 -
Hi @alihasanahmedk
