残り時間も環境もリセットされた

$ kubectl create ns argo

この辺のpodが立ち上がる

$ kubectl create serviceaccount argo-workflow -n argo

code:bash

controlplane:~$ cat <<EOF | kubectl apply -f - >/dev/null

apiVersion: rbac.authorization.k8s.io/v1

kind: ClusterRole

metadata:

name: workflow-executor-rbac

rules:

- apiGroups:

- argoproj.io

resources:

- workflowtaskresults

verbs:

- create

- patch

EOF

controlplane:~$ cat <<EOF | kubectl apply -f - >/dev/null

apiVersion: rbac.authorization.k8s.io/v1

kind: ClusterRoleBinding

metadata:

name: argo-executor-binding

roleRef:

apiGroup: rbac.authorization.k8s.io

kind: ClusterRole

name: workflow-executor-rbac

subjects:

- kind: ServiceAccount

name: argo-workflow

namespace: argo

EOF

$ kubectl -n argo apply -f hello-workflow.yaml

code:hello-workflow.yaml

apiVersion: argoproj.io/v1alpha1

kind: Workflow

metadata:

name: hello

spec:

serviceAccountName: argo-workflow

entrypoint: main

templates:

- name: main

container:

image: busybox

$ kubectl -n argo wait workflows/hello --for condition=Completed --timeout 2m

終わるまで明示的に待てる

UIログインをバイパスできるように認証モードをサーバに切り替え

code:bash

kubectl patch deployment \

argo-server \

--namespace argo \

--type='json' \

-p='[{"op": "replace", "path": "/spec/template/spec/containers/0/args", "value": [

"server",

"--auth-mode=server",

"--secure=false"

]},

{"op": "replace", "path": "/spec/template/spec/containers/0/readinessProbe/httpGet/scheme", "value": "HTTP"}

]'

よくわかってないがこれは本番環境でやるべきではないらしい

create直後は黄色になっている

数秒後に緑になる

いったんymlでworkflow作って、

もう一つはGUI上で別のworkflowを作ったってことか

左上で、resubmitとかもできる

code:bash

gunzip argo-linux-amd64.gz

chmod +x argo-linux-amd64

mv ./argo-linux-amd64 /usr/local/bin/argo

$ argo version

workflowを実行する

workflowのリスト

$ argo list -n argo

code:bash

controlplane:~$ argo list -n argo

NAME STATUS AGE DURATION PRIORITY MESSAGE

hello-world-lm6sh Succeeded 35s 10s 0

hello-world-7dttr Succeeded 2m 10s 0

hello-world-s5nck Succeeded 6m 10s 0
