我有一个配置了 jib-maven 的 Spring Boot 应用程序

聚甲醛 

<plugin>
<groupId>com.google.cloud.tools</groupId>
<artifactId>jib-maven-plugin</artifactId>
<version>2.1.0</version>
<configuration>
    <from>
        <image>openjdk:11-jre-slim</image>
    </from>
    <to>
        <image>registry.demo/${project.artifactId}</image>
        <tags>
            <tag>${project.version}</tag>
        </tags>
        <tags>
            <tag>latest</tag>
        </tags>
    </to>
    <container>
        <jvmFlags>
            <jvmFlag>-XX:+UseContainerSupport</jvmFlag>
            <jvmFlag>-XX:MinRAMPercentage=60.0</jvmFlag>
            <jvmFlag>-XX:MaxRAMPercentage=90.0</jvmFlag>
            <jvmFlag> -XshowSettings:vm</jvmFlag>
        </jvmFlags>
        <mainClass>com.demo.DemoApplication</mainClass>
    </container>
</configuration>

SKAFFOLD.YAML

        apiVersion: skaffold/v2beta1
        kind: Config
        metadata:
        name: springtokube
        build:
        artifacts:
        - image: registry.demo/springtokube
            jib:
            project: com.demo:springtokube
        local:
            push: true
            concurrency: 1
            useBuildkit: false
            useDockerCLI: true
        deploy:
        kubectl:
            manifests:
            - deployment.yaml

还设置不安全的注册表 

skaffold config set --global insecure-registries  registry.demo

但是当使用minikube时我可以成功运行 

skaffold dev

当使用其他集群（ON-PREM）时，我得到

FATA[0016] exiting dev mode because first build failed: build failed: building [registry.demo/springtokube]: build artifact: getting image: GET http://registry.demo/v2/: : Not Found

可能是什么问题？

我今天使用 kubectl 上下文重新启动

skaffold debug --no-prune=false --cache-artifacts=false

它失败了

我认为 minikube 有效。但是禁用缓存无法构建

如果我跑

 skaffold debug OR  skaffold dev

工作正常

但是如果我在禁用缓存的情况下运行

skaffold debug --no-prune=false --cache-artifacts=false

失败它显示上面的日志

经过几天的挣扎，我找到了解决方案。

按照 Brian de Alwis的建议，我能够让Skaffold使用Self Signed Certificate。

Skaffold build 或 dev不使用放入的证书。

/etc/docker/certs.d/myregistrydomain.com/ca.crt

该路径仅供docker 客户端使用。

解决方案是将您的注册表证书放入

 /usr/local/share/ca-certificates/myregistrydomain.com.crt

然后 

update-ca-certificates

检查链接以获取更多信息

如果您使用自签名证书，则脚手架 yaml 文件中不需要不安全的注册表

apiVersion: skaffold/v2beta1
kind: Config
metadata:
  name: springtokube
build:
#  insecureRegistries:
#    - myregistrydomain.com

或运行skaffold与

skaffold dev --insecure-registry=myregistrydomain.com

希望这可以帮助其他人努力使skaffold使用自签名证书
