            Add a simple A record to the CoreDNS service on Kubernetes
            Asked 2022-Feb-15 at 16:36

            Here is the issue: We have several microk8s cluster running on different networks; yet each have access to our storage network where our NAS are.

            within Kubernetes, we create disks with an nfs-provisionner (nfs-externalsubdir). Some disks were created with the IP of the NAS server specified. Once we had to change the IP, we discovered that the disk was bound to the IP, and changing the IP meant creating a new storage resource within.

            To avoid this, we would like to be able to set a DNS record on the Kubernetes cluster level so we could create storage resources with the nfs provisionner based on a name an not an IP, and we could alter the DNS record when needed (when we upgrade or migrate our external NAS appliances, for instance) for instance, I'd like to tell every microk8s environnements that:

            192.168.1.4 my-nas.mydomain.local

            ... like I would within the /etc/hosts file.

            Is there a proper way to achieve this? I tried to follow the advices on this link: Is there a way to add arbitrary records to kube-dns? (the answer upvoted 15 time, the cluster-wise section), restarted a deployment, but it didn't work

            I cannot use the hostAliases feature since it isn't provided on every chart we are using, that's why I'm looking for a more global solution.

            You can set you custom DNS in K8s using the Kube-DNS (Core-DNS)

            You have to inject/pass the configuration file as configmap to Core DNS volume.

            How to start an Ingress Controller with flags? (microk8s)
            Asked 2022-Jan-25 at 11:40

            Usually i am able to find most things by searching on the web - however in this case, the instructions on the web talk about - probably very basic stuff that i don't get yet.

            What i am trying to achieve: i am trying to install argocd, using microk8s and nginx-ingress. Right now i am stuck at enabling the SSL passthrough for argocd. Currently i configured an ingress-controller according to the instructions of the argocd-documentation and the ingress-controller runs without errors.

            My guess is that as it's mentioned everywhere that i have to start the ingress controller with the "--enable-ssl-passthrough"-flag.

            https://kubernetes.github.io/ingress-nginx/user-guide/nginx-configuration/annotations/#ssl-passthrough "SSL Passthrough is disabled by default and requires starting the controller with the --enable-ssl-passthrough flag."

            Now my problem: How do i do that? - for me, the ingress controller is "just always running". I can delete and recreate the controller with the kubectl-command "create -f ingress.yaml" - which creates an ingress within the argocd-namespace.

            i kind of lack the basics of kubernetes and don't get how i could stop and restart the ingress-controller with flags (perhaps i mistake what the "ingress controller" is too). Does anyone have an idea how i could achieve that?

            You may want to check CVE-2021-25742: Ingress-nginx custom snippets. I put in bold interested for you part.

            annotation-value-word-blocklist defaults are "load_module,lua_package,_by_lua,location,root,proxy_pass,serviceaccount,{,},',"

            Users from mod_security and other features should be aware that some blocked values may be used by those features and must be manually unblocked by the Ingress Administrator.

            It seems to me your issue related to mod_security + above blocklist, that contains ' symbol.

            In order to fix your issue you should either

            • set the value of annotation-value-word-blocklist to an empty string ""

            or

            I found out that you can actually check for certificates with kubectl: kubectl get certificate -n production

            The status of this certificate was READY = FALSE.

            I checked the description: kubectl describe certificate -n production

            At the bottom it said: Too many certificates have been created in the last 164 hours for this exact domain.

            I just changed the domain and voila! It works.

            I would like to deploy an ngingx-ingress controller on my self-hosted Kubernetes (microk8s) that is configurable to listen on one or more interfaces (external IPs).

            For above scenario, you have to deploy the multiple ingress controller of Nginx ingress and keep the different class name in it.

            Official document : https://kubernetes.github.io/ingress-nginx/user-guide/multiple-ingress/

            So in this scenario, you have to create the Kubernetes service with Loadbalancer IP and each will point to the respective deployment and class will be used in the ingress object.

            If you looking forward to use the multiple domains with a single ingress controller you can easily do it by mentioning the host into ingress.

            Example for two domain :

            1. bar.foo.dev
            2. foo.bar.dev

            In this case problem with connection has been resolved by setting spec.selector.

            The .spec.selector field defines how the Deployment finds which Pods to manage. In this case, you select a label that is defined in the Pod template (app: nginx).

            .spec.selector is a required field that specifies a label selector for the Pods targeted by this Deployment.
