We arent going to install cert-manager. User expresses they want TLS. If we find the Certificate CR, then we program it
What's the proposal then for how cert-manager should be installed? Just manually in to the cluster?
I don't know your design goals, but this was feeling to me like "bring me a cluster, give me access, deploy your apps with easy commands". Darren just said in the Webinar:
This feels like "No knowledge of Kubernetes YAML required, FOOTNOTE: unless you want to use your own domain name and use TLS with it". Hopefully it's reconsidered, having Acorn install cert-manager for you unless already installed/available.
Ahhh, I took the wording of the issue to be almost like a "we won't be doing this", but I guess it's just pending, based on:
In the future, Acorn will provide built-in mechanisms to automatically provide certificates for each endpoint. Today, adding a certificate must follow the manual approach.
@andyjeffries There's a balance we're trying to find the right line on between batteries-included (you just want a cert, I don't know or care about CertManager) and tolerable-for-cluster-operator-to-install. The more stuff we add to someone's cluster the more they worry about trying it, compatibility between versions issues, should it be cleaned up on uninstall, etc.
CertManager does a lot of stuff and we don't even actually need so one option we're considering is not requiring it at all by doing ACME dances in the controller instead. That's straightforward enough for single name http-01 challenges.
The part CertManager does do that's really useful is taking creds and talking to all the provider APIs for dns-01/wildcards. But we can maybe do a one-time setup _acme_challenge.yourdomain.com CNAME [your-cluster].on-acorn.io
yourself step, and then with that we can manage a *.yourdomain.com wildcard without having any creds or provider-specific implementation.
Not requiring (or self-embedding the relevant parts of) cert-manager would be cool.
I definitely lean to the "I have a cluster, but want acorn to manage it as a kind-of/lightweight PAAS for me" camp.
I know about Kubernetes (as former CTO of Civo.com), but I don't want to deal with the minutia of it in my new job as it's not necessary for me.
Right now, our implementation plans in this area are as follows:
Hello there. Acorn is not finding a TLS secret!? I just tried several times it is not working.
Acorn will automatically inspect each certificate in the Acorn namespace for one that can be used with my-app.example.com. If no TLS secret is found with that FQDN, it will be exposed on HTTP only.

I have a TLS secrets that external secrets operator created from GCP SM. $ k get secret sbx-huma-com-tls-secret -n todo-app-acorn-cd495f1f-791
It looks like you are creating the secret in the generated namepsace that acorn creates. For this auot-detect feature to work, you want to add the secret to the user-facing namespace (acorn
by default).
I use external-dns so I need to put an annotation. "external-dns.alpha.kubernetes.io/hostname": "todo-app-acorn-1.sbx.huma.com" annotation
I didn't realize external-dns relied on an annotation being on the ingress. I am currently working a feature to support the addition of arbitrary user-defined labels and annotations to be added to the resources created by acorn. Should be out in the next week or two.

Here is link to its docs Annotate the Service with your desired external DNS name. Make sure to change example.org to your domain.
kubectl annotate service nginx "external-dns.alpha.kubernetes.io/hostname=nginx.example.org."

IMHO not intuitive at all. When I feed my TLS secrets to my operator, I create secrets in each namespace, because this allows to cover tenant per namespace case.

Roger that. Hopefully when the annotation feature lands, it will meet your needs.

I hear you. That just hits a chicken-and-egg problem of adding the secrets after acorn has created and deployed everything. We have another feature in the queue for being to tell acorn to create its k8s resources in a pre-defined/pre-created namespace rather than a generated one. When that feature lands, you'd be able to drop the tls secret into namespace X and then deploy deploy there.
That said, as the feature stands now, I think you can still might be able to achieve what you desire. You can have a user-facing "acorn" namespace per tenant, rather than just using the default acorn
namespace. You'd need setup some RBAC to ensure each tenant can only create acorn Apps in their namespace and no others.
do Acorn want me to name a secret some way? It doesn't pick up my secret.

Can you provide a dump of the cert (not the private key). Like openssl x509 -in cert.pem -noout -text

@cjellick do you want to say what I was doing an unexpected way of deploying?
It should I put secrets for my workload into acorn

Acorn creates a bunch of secrets that are empty in the acorn
namespace. Are they supposed to be filled? Than why do they have random suffixes? I got confused.

Yeah, wild card support hasn't been added/tested. It is on the list of items to add.
Do Acorn v0.1.4 support one certificate/tls-secret for 2 dnsNames at the moment? Is it a case of not supporting TLS for default "container.app.domain"?

@denist-huma Here is what I tried, and it seems to be working as expected. Can you let me know if my setup is different from yours?
It looks like the info you last provided, Acorn is recognizing the appropriate certificate to use for each of the domain names. I wonder if this is more of a cert issue?

@cloudnautique Thank you, I think it works as expected.
Both return for Chrome: NET::ERR_CERT_AUTHORITY_INVALID, for Firefox MOZILLA_PKIX_ERROR_SELF_SIGNED_CERT. That is expected.
What I had before was due to browser's cache, https://github.com/acorn-io/acorn/issues/486#issuecomment-1224082048 is solved.
Can this issue be closed?
@cjellick The topic of this issue is the Acorn supporting TLS out of the box, so probably can't close yet until we merge the annotations? Or we keep going to provide something completely end to end.
@denist-huma I was able to verify that Wild Card certs do work as expected. From my previous example in https://github.com/acorn-io/acorn/issues/486#issuecomment-1224235479 I changed the cert to:
apiVersion: cert-manager.io/v1
kind: Certificate
metadata:
name: registry-studio-cert
spec:
dnsNames:
- "*.studio-rd.cloudnautique.com"
issuerRef:
group: cert-manager.io
kind: ClusterIssuer
name: cloudflare-issuer
secretName: wc-tls-secret
The certificate secret was applied to the Ingress resource correctly.
I changed the dnsNames to *.cloudnautique.com
and it correctly did NOT assign the cert secret to the ingress.
So it does appear wild card support is working.
Please let me know if you are still running into issues.
Right on. My bad
@ibuildthecloud thank you, following you I tried one more time. In my setup I if both the self-signed cert "todo-app-tls-secret" and my *.sbx.huma TLS secrets present in the "acorn" ns, then Acorn do a thing I don't get:
*.sbx.huma
TLS for todo-app-acorn-1.sbx.huma.com
server.todo-app-acorn.sbx.huma.com
$ k get secrets -n todo-app-acorn-697a2486-a79 | grep tls
pp-star-sbx-huma-com-secret-a1c5d9fc-f76 kubernetes.io/tls 2 13m
todo-app-tls-secret-c3905a21-d65 kubernetes.io/tls 3 13m
$ k get secrets -n acorn | grep tls
pp-star-sbx-huma-com-secret kubernetes.io/tls 2 18m
todo-app-tls-secret kubernetes.io/tls 3 24h
I did acorn rm
and acorn run
again, no changes. Clear browser data, restart browser not helps.
@denist-huma the cert would need to be for *.todo-app-acorn.sbx.huma.com
. Wild cards are only valid for one level.
how can I disable the publishing of server.todo-app-acorn.sbx.huma.com
?
Change the ports: publish: "8090/http"
to "ports: expose: "8090/http"
or remove it completely from acornfile and supply at run?
acorn run -n todo-app-acorn --publish todo-app-acorn-1.sbx.huma.com:server .
We went back and forth on whether to also create the generated-name endpoint if you explicit set and endpoint. We ultimately decided to create it, but your concern makes sense. We'll change the behavior to not create a generated-name endpoint when you've explicitly set one.
Here's the tracking issue: https://github.com/acorn-io/acorn/issues/383
@cjellick Yes that makes sense. :+1: My concern is that acorn should not "make an offer one cannot refuse" :) (c) Godfather
This issue has a lot of history and went in a couple different directions. We do want to support out-of-the-box, no-cert-manager-needed issuance of certificates for user provided domains. That is tracked here: https://github.com/acorn-io/acorn/issues/206
While the other issue will be the primary tracking issue for this feature, I am going to keep this issue open as a "sibling" issue to that one and when that feature is completed, we will close both these issues.
Feature is looking good. I opened up two follow up issues: https://github.com/acorn-io/acorn/issues/900 https://github.com/acorn-io/acorn/issues/901
closing this main issue as completed
This is NOT for on-acorn.io domains
This is for the case where user supplies their own cluster domain, or even more likely creates an app with the following publish flag:
Supporting this means installing and managing cert-manager and auto-creating the
Certificate
CRs if the app wants TLS
