我正坐在公司防火墙后面,该公司防火墙仅允许https流量通过MITM证书进行拦截。不幸的是,链接程序和大多数其他服务网格在所有Pod代理通信之间都启用了mTLS。如何禁用mTLS,以使链接的Pod不会在我的网络中被阻止?
$ linkerd install > linkerd.yaml
$ linkerd inject --ignore-cluster --manual --disable-identity --disable-tap linkerd.yaml >> afterInject.yaml
$ kubectl apply -f afterInject.yaml
有趣的是,正在使用以下命令收集链接器的度量标准:
linkerd metrics -n linkerd $(
kubectl --namespace linkerd get pod \
--selector linkerd.io/control-plane-component=controller \
--output name
)
Linkerd仍在使用这些日志在linkerd命名空间中部署tap
$ kubectl logs -n linkerd linkerd-tap-6c845f67cd-wzzp4 tap

此外,我在kubeapi服务器上遇到以下错误
controller.go:114] loading OpenAPI spec for "v1alpha1.tap.linkerd.io" failed with: failed to retrieve openAPI spec, http error: ResponseCode: 503, Body: Error trying to reach service: 'dial tcp 10.108.135.128:443: i/o timeout', Header: map[Content-Type:[text/plain; charset=utf-8] X-Content-Type-Options:[nosniff]]
使这个更奇怪的是我的链接器检查说一切都很好:

我还向其他正常工作的集群添加了taefik入口规则,并且无法访问仪表板:
apiVersion: v1
kind: Secret
type: Opaque
metadata:

namespace: linkerd
data:
auth: private value...
# generated with htpassword
# then base 64 encoded

spec:
rules:
- host: linkerd-dashboard.private.com

尽管它似乎应该可以工作:
$ kubectl get ing -n linkerd

web-ingress <none> linkerd-dashboard.private.com x.x.x.x 80 42m

很高兴得知您了解了@mikeLundquist。
要回答原始问题,您通过在安装时指定以下标志来完全禁用mTLS:
--disable-identity
--disable-tap
对于头盔用户,您可以在disableIdentity: true
section下的Linkerd头盔图中添加disableTap: true
和proxy
。
