5.7.2. 在 Operator Lifecycle Manager 中测试 Operator 升级

流程

1. 如果使用 run bundle 子命令的 OLM 尚未安装 Operator，请通过指定捆绑包镜像来安装 Operator 的早期版本。例如，对于 Memcached Operator：

   $ operator-sdk run bundle <registry>/<user>/memcached-operator:v0.0.1

   Copy to Clipboard Toggle word wrap

   输出示例

   INFO[0009] Successfully created registry pod: quay-io-demo-memcached-operator-v0-0-1
   INFO[0009] Created CatalogSource: memcached-operator-catalog
   INFO[0010] OperatorGroup "operator-sdk-og" created
   INFO[0010] Created Subscription: memcached-operator-v0-0-1-sub
   INFO[0013] Approved InstallPlan install-bqggr for the Subscription: memcached-operator-v0-0-1-sub
   INFO[0013] Waiting for ClusterServiceVersion "my-project/memcached-operator.v0.0.1" to reach 'Succeeded' phase
   INFO[0013]   Waiting for ClusterServiceVersion "my-project/memcached-operator.v0.0.1" to appear
   INFO[0019]   Found ClusterServiceVersion "my-project/memcached-operator.v0.0.1" phase: Succeeded

   Copy to Clipboard Toggle word wrap

2. 通过为后续的 Operator 版本指定捆绑包镜像来升级已安装的 Operator：

   $ operator-sdk run bundle-upgrade <registry>/<user>/memcached-operator:v0.0.2

   Copy to Clipboard Toggle word wrap

   输出示例

   INFO[0002] Found existing subscription with name memcached-operator-v0-0-1-sub and namespace my-project
   INFO[0002] Found existing catalog source with name memcached-operator-catalog and namespace my-project
   INFO[0009] Successfully created registry pod: quay-io-demo-memcached-operator-v0-0-2
   INFO[0009] Updated catalog source memcached-operator-catalog with address and annotations
   INFO[0010] Deleted previous registry pod with name "quay-io-demo-memcached-operator-v0-0-1"
   INFO[0041] Approved InstallPlan install-gvcjh for the Subscription: memcached-operator-v0-0-1-sub
   INFO[0042] Waiting for ClusterServiceVersion "my-project/memcached-operator.v0.0.2" to reach 'Succeeded' phase
   INFO[0042]   Found ClusterServiceVersion "my-project/memcached-operator.v0.0.2" phase: InstallReady
   INFO[0043]   Found ClusterServiceVersion "my-project/memcached-operator.v0.0.2" phase: Installing
   INFO[0044]   Found ClusterServiceVersion "my-project/memcached-operator.v0.0.2" phase: Succeeded
   INFO[0044] Successfully upgraded to "memcached-operator.v0.0.2"

   Copy to Clipboard Toggle word wrap

3. 清理已安装的 Operator：

   $ operator-sdk cleanup memcached-operator

   Copy to Clipboard Toggle word wrap
