Hello All,
I am following Dan Walsh’s SysAdmin article
(https://developers.redhat.com/blog/2019/08/14/best-practices-for-running-...)
to speed up our CI builds in Jenkins.
I am trying to do what’s suggested under “Additional stores”, basically volume mounting
the directory where the containerd stores on the K8s host into a container under
/var/lib/shared.
We are running containerd as the runtime on an EKS cluster.
According to the article, I need to do:
# mkdir /var/lib/containers4
# podman run -v ./build:/build:z -v /var/lib/containers/storage:/var/lib/shared:ro -v \
/var/lib/containers4:/var/lib/containers:Z
quay.io/buildah/stable<http://quay.io/buildah/stable> \
buildah -t image4 bud /build
# podman run -v /var/lib/containers/storage:/var/lib/shared:ro \
-v >/var/lib/containers4:/var/lib/containers:Z
quay.io/buildah/stable<http://quay.io/buildah/stable> buildah push image4 \
registry.company.com/myuser<http://registry.company.com/myuser>
Can someone please tell me the equivalent directory for /var/lib/containers/storage? I.e
where does containerd store the download images on the Kubernetes worker nodes?
The containerd config looks like this:
# cat /etc/containerd/config.toml
version = 2
root = "/var/lib/containerd"
state = "/run/containerd"
[grpc]
address = "/run/containerd/containerd.sock"
[plugins."io.containerd.grpc.v1.cri".containerd]
default_runtime_name = "runc"
[plugins."io.containerd.grpc.v1.cri"]
sandbox_image =
“XXXXXXXX.amazonaws.com/eks/pause:3.5<http://XXXXXXXX.amazonaws.com/eks/pause:3.5>"
[plugins."io.containerd.grpc.v1.cri".containerd.runtimes.runc]
runtime_type = "io.containerd.runc.v2"
[plugins."io.containerd.grpc.v1.cri".containerd.runtimes.runc.options]
SystemdCgroup = true
[plugins."io.containerd.grpc.v1.cri".cni]
bin_dir = "/opt/cni/bin"
conf_dir = "/etc/cni/net.d"
Thanks in advance.
