OpenShift 4.2 etcd operatorhub离线环境部署

本文记录在OperatorHub中存在界面但缺少镜像的环境下如何安装部署。感谢王征提供的大力支持和指导。

现在一个在线环境找到etcd所需要的镜像

quay.io/coreos/etcd-operator@sha256:66a37fd61a06a43969854ee6d3e21087a98b93838e284a6086b13917f96b0d9b

quay.io/coreos/etcd:v3.2.13

docker.io/library/busybox:1.28.-glibc

找一个能上网的机器，建立registry.redhat.ren的docker-distribution,通过oc image mirror命令把镜像的相关信息复制到本地

oc image mirror quay.io/coreos/etcd-operator@sha256:66a37fd61a06a43969854ee6d3e21087a98b93838e284a6086b13917f96b0d9b registry.redhat.ren/quay.io/coreos/etcd-operator

将本地的registry打包成tgz文件，

tar zcvf registry-etcd.tgz registry

然后上传到自己离线的registry,然后解压。

修改helper机器上的image.registries.conf，添加如下记录

[[registry]]

  location = "quay.io/coreos/etcd-operator"

  insecure = false

  blocked = false

  mirror-by-digest-only = false

  prefix = ""

  [[registry.mirror]]

    location = "registry.redhat.ren/quay.io/coreos/etcd-operator"

    insecure = true

[[registry]]

  location = "docker.io/library/busybox"

  insecure = false

  blocked = false

  mirror-by-digest-only = false

  prefix = ""

  [[registry.mirror]]

    location = "registry.redhat.ren/docker.io/library/busybox"

    insecure = true

[[registry]]

  location = "quay.io/coreos/etcd"

  insecure = false

  blocked = false

  mirror-by-digest-only = false

  prefix = ""

  [[registry.mirror]]

    location = "registry.redhat.ren/quay.io/coreos/etcd"

    insecure = true

然后运行

config_source=$(cat ./image.registries.conf | python3 -c "import sys, urllib.parse; print(urllib.parse.quote(''.join(sys.stdin.readlines())))"  )

cat <<EOF > -worker-container-registries.yaml

apiVersion: machineconfiguration.openshift.io/v1

kind: MachineConfig

metadata:

  labels:

    machineconfiguration.openshift.io/role: worker

  name: -worker-container-registries

spec:

  config:

    ignition:

      version: 2.2.

    storage:

      files:

      - contents:

          source: data:text/plain,${config_source}

          verification: {}

        filesystem: root

        mode:

        path: /etc/containers/registries.conf

EOF

cat <<EOF > -master-container-registries.yaml

apiVersion: machineconfiguration.openshift.io/v1

kind: MachineConfig

metadata:

  labels:

    machineconfiguration.openshift.io/role: master

  name: -master-container-registries

spec:

  config:

    ignition:

      version: 2.2.

    storage:

      files:

      - contents:

          source: data:text/plain,${config_source}

          verification: {}

        filesystem: root

        mode:

        path: /etc/containers/registries.conf

EOF

oc apply -f ./-worker-container-registries.yaml -n openshift-config

oc apply -f ./-master-container-registries.yaml -n openshift-config

通过podman push把另外两个镜像推入到正确的位置，然后安装etcd Operator, 再建立etcd cluster.

[root@helper ocp4]# oc get pods
