すぐoc get pod --all-namespaces -o wide | grep ${node-name}やっちゃうんだけど、、、
v3だと便利コマンドありました。
※ 以下、小ネタです。(こんなコマンドもあるんだなー程度で見てください。たぶんストレートにgrepした方が早いです笑)
OCV v3
v3はoc adm manage-node ${node-name} --list-podsというコマンドがある。
ノードokd-node2.esxi.jp-z.jpで動いてるpod一覧を表示するには、以下のように実行。
[zaki@okd-master ~]$ oc adm manage-node okd-node2.esxi.jp-z.jp --list-pods Listing matched pods on node: okd-node2.esxi.jp-z.jp NAMESPACE NAME READY STATUS RESTARTS AGE openshift-infra hawkular-cassandra-1-dcdvx 1/1 Running 4 13d openshift-infra heapster-tgk79 1/1 Running 4 13d openshift-logging logging-fluentd-nw8gv 0/1 CrashLoopBackOff 124 13d openshift-monitoring node-exporter-8wp7c 2/2 Running 8 13d openshift-node sync-7dkbb 1/1 Running 4 13d openshift-sdn ovs-wp9qx 1/1 Running 4 13d openshift-sdn sdn-q25zn 1/1 Running 4 13d s2i-sample sample-1-build 0/1 Completed 0 10d s2i-sample sample-2-build 0/1 Completed 0 10d
oc describe nodeでも(Running状態であれば)見れる。

OCP v4
ドキュメントとコマンドのヘルプを見る限り、v4からoc adm manage-nodeが無くなってる。(なんでだろ)
なのでoc describe nodeするしかない模様。
[zaki@okd4-manager ~]$ oc describe node okd4-worker0 Name: okd4-worker0 Roles: worker : : Non-terminated Pods: (18 in total) Namespace Name CPU Requests CPU Limits Memory Requests Memory Limits AGE --------- ---- ------------ ---------- --------------- ------------- --- openshift-cluster-node-tuning-operator tuned-sqvb7 10m (0%) 0 (0%) 50Mi (0%) 0 (0%) 9d openshift-console downloads-cf5d8d7f4-9wtkf 10m (0%) 0 (0%) 50Mi (0%) 0 (0%) 9d openshift-csi-snapshot-controller-operator csi-snapshot-controller-operator-5f5b588bf9-2ghlk 10m (0%) 0 (0%) 50Mi (0%) 0 (0%) 9d openshift-dns dns-default-bzmq7 110m (7%) 0 (0%) 70Mi (0%) 512Mi (6%) 9d openshift-image-registry image-registry-7f44857cc-h6znx 100m (6%) 0 (0%) 256Mi (3%) 0 (0%) 9d openshift-image-registry node-ca-8dk7l 10m (0%) 0 (0%) 10Mi (0%) 0 (0%) 9d openshift-ingress router-default-5698995cc8-5z8r4 100m (6%) 0 (0%) 256Mi (3%) 0 (0%) 9d openshift-machine-config-operator machine-config-daemon-wt5lx 40m (2%) 0 (0%) 100Mi (1%) 0 (0%) 9d openshift-marketplace community-operators-59754d9959-pglxz 10m (0%) 0 (0%) 100Mi (1%) 0 (0%) 16m openshift-monitoring alertmanager-main-2 110m (7%) 100m (6%) 245Mi (3%) 25Mi (0%) 9d openshift-monitoring node-exporter-lfsq4 112m (7%) 0 (0%) 200Mi (2%) 0 (0%) 9d openshift-monitoring prometheus-adapter-d48bc96cc-z8lj2 10m (0%) 0 (0%) 20Mi (0%) 0 (0%) 8d openshift-monitoring prometheus-k8s-1 480m (32%) 200m (13%) 1234Mi (16%) 50Mi (0%) 9d openshift-multus multus-sfwfb 10m (0%) 0 (0%) 150Mi (2%) 0 (0%) 9d openshift-sdn ovs-jh5x4 200m (13%) 0 (0%) 400Mi (5%) 0 (0%) 9d openshift-sdn sdn-sq7q2 100m (6%) 0 (0%) 200Mi (2%) 0 (0%) 9d s2i-git-perl s2i-sample-4-mk5s4 0 (0%) 0 (0%) 0 (0%) 0 (0%) 8d s2i-sample sample-2-q4wnv 0 (0%) 0 (0%) 0 (0%) 0 (0%) 8d Allocated resources: : :
ちなみにv4(というかk8sのver 1.14)から--all-namespacesの短縮オプションで-Aが使えるので割と楽。
