以上是我参考的链接
测试3.py：
import yaml
from kubernetes import client, config
config.load_kube_config()
txt = ""
with open("/home/xxxxxx/ide-ingress/b3a1e295-d77c-41b4-a2e6-5cb75b7b2f61.yaml", 'r') as f:
for a in f.readlines():
txt = txt + a
res = list(yaml.safe_load_all(txt))
deployment_dict = res[3]
def create_deployment(apps_v1_api):
container = client.V1Container(
name=deployment_dict.get("metadata").get("name"),
image=deployment_dict.get("spec").get("template").get("spec").get("containers")[0].get("image"),
image_pull_policy=deployment_dict.get("spec").get("template").get("spec").get("containers")[0].get(
"imagePullPolicy"),
ports=[client.V1ContainerPort(container_port=3000)],
)
template = client.V1PodTemplateSpec(
metadata=client.V1ObjectMeta(labels=deployment_dict.get("metadata").get("labels")),
spec=client.V1PodSpec(containers=[container]))
spec = client.V1DeploymentSpec(
selector=deployment_dict.get("spec").get("selector").get("matchLabels"),
replicas=1,
template=template)
deployment = client.V1Deployment(
api_version=deployment_dict.get("apiVersion"),
kind=deployment_dict.get("kind"),
metadata=client.V1ObjectMeta(name=deployment_dict.get("metadata").get("name")),
spec=spec)
response3 = apps_v1_api.create_namespaced_deployment(
namespace=deployment_dict.get("metadata").get("namespace"), body=deployment
)
print(response3)
print(deployment_dict.get("spec").get("selector").get("matchLabels"))
def main():
config.load_kube_config()
apps_v1_api = client.AppsV1Api()
create_deployment(apps_v1_api)
if __name__ == "__main__":
main()
然后我得到了错误：
{'app': 'b3a1e295-d77c-41b4-a2e6-5cb75b7b2f61'}

错误信息提示我空选择器对部署无效，但我打印的选择器也很有价值。API里面应该有value，但是报错，没有成功，不知道为什么。
