能力管理

在 KubeVela 中,开发者可以从任何包含 OAM 抽象文件的 GitHub 仓库中安装更多的能力(例如:新 component 类型或者 traits )。我们将这些 GitHub 仓库称为 Capability Centers

KubeVela 可以从这些仓库中自动发现 OAM 抽象文件,并且同步这些能力到我们的 KubeVela 平台中。

添加能力中心#

新增且同步能力中心到 KubeVela:

$ vela cap center config my-center https://github.com/oam-dev/catalog/tree/master/registry
successfully sync 1/1 from my-center remote center
Successfully configured capability center my-center and sync from remote
$ vela cap center sync my-center
successfully sync 1/1 from my-center remote center
sync finished

现在,该能力中心 my-center 已经可以使用。

列出能力中心#

你可以列出或者添加更多能力中心。

$ vela cap center ls
NAME ADDRESS
my-center https://github.com/oam-dev/catalog/tree/master/registry

[可选] 删除能力中心#

删除一个

$ vela cap center remove my-center

列出所有可用的能力中心#

列出某个中心所有可用的能力。

$ vela cap ls my-center
NAME CENTER TYPE DEFINITION STATUS APPLIES-TO
clonesetservice my-center componentDefinition clonesets.apps.kruise.io uninstalled []

从能力中心安装能力#

我们开始从 my-center 安装新 component clonesetservice 到你的 KubeVela 平台。

你可以先安装 OpenKruise 。

helm install kruise https://github.com/openkruise/kruise/releases/download/v0.7.0/kruise-chart.tgz

my-center 中安装 clonesetservice component 。

$ vela cap install my-center/clonesetservice
Installing component capability clonesetservice
Successfully installed capability clonesetservice from my-center

使用新安装的能力#

我们先检查 clonesetservice component 是否已经被安装到平台:

$ vela components
NAME NAMESPACE WORKLOAD DESCRIPTION
clonesetservice vela-system clonesets.apps.kruise.io Describes long-running, scalable, containerized services
that have a stable network endpoint to receive external
network traffic from customers. If workload type is skipped
for any service defined in Appfile, it will be defaulted to
`webservice` type.

很棒!现在我们部署使用 Appfile 部署一个应用。

$ cat << EOF > vela.yaml
name: testapp
services:
testsvc:
type: clonesetservice
image: crccheck/hello-world
port: 8000
EOF
$ vela up

Port forward: vela port-forward testapp
SSH: vela exec testapp
Logging: vela logs testapp
App status: vela status testapp
Service status: vela status testapp --svc testsvc

随后,该 cloneset 已经被部署到你的环境。

$ kubectl get clonesets.apps.kruise.io
NAME DESIRED UPDATED UPDATED_READY READY TOTAL AGE
testsvc 1 1 1 1 1 46s

删除能力#

注意,删除能力前请先确认没有被应用引用。

$ vela cap uninstall my-center/clonesetservice
Successfully uninstalled capability clonesetservice
