I'm running into an issue handling tls certificates with cert-manager, I'm following the documentation and added some extras to work with Traefik
as an ingress.
Currently, I have this YAML
files:
cluster-issuer.yaml
apiVersion: cert-manager.io/v1alpha2
kind: ClusterIssuer
metadata:
name: letsencrypt-staging
namespace: secure-alexguedescom
spec:
acme:
email: [email protected]
server: https://acme-staging-v02.api.letsencrypt.org/directory
privateKeySecretRef:
# Secret resource used to store the account's private key.
name: letsencrypt-staging
# Add a single challenge solver, HTTP01 using nginx
solvers:
- selector: {}
http01:
ingress:
class: traefik-cert-manager
traefik-ingress.yaml
apiVersion: extensions/v1beta1
kind: Ingress
metadata:
annotations:
# add an annotation indicating the issuer to use.
cert-manager.io/cluster-issuer: letsencrypt-staging
name: secure-alexguedescom-ingress-http
namespace: secure-alexguedescom
spec:
rules:
- host: secure.alexguedes.com
http:
paths:
- backend:
serviceName: secure-alexguedescom-nginx
servicePort: 80
path: /
tls:
- hosts:
- secure.alexguedes.com
secretName: secure-alexguedescom-cert
cert-staging.yaml
apiVersion: cert-manager.io/v1alpha2
kind: Certificate
metadata:
name: secure-alexguedescom-cert
namespace: secure-alexguedescom
spec:
commonName: secure.alexguedes.com
secretName: letsencrypt-staging
dnsNames:
- secure.alexguedes.com
issuerRef:
name: letsencrypt-staging
kind: ClusterIssuer
Inspecting the certs I have this error message:
Message: Issuing certificate as Secret does not contain a certificate
Reason: MissingData
Also inspecting the certificaterequest
I have this log messages:
Status:
Conditions:
Last Transition Time: 2020-08-16T00:32:01Z

Normal OrderPending 11m cert-manager Waiting on certificate issuance from order secure-alexguedescom/secure-alexguedescom-cert-q8w5p-1982372682: ""
I'm not sure which piece is wrong, using Helm v2 with Tiller and k8s v1.7
Any ideas?
Thanks in advance
The typical problem with letsencrypt certs is the letsencrypt itself not being able to validate who you are and that you own the domain. In this case, alexguedes.com
.
With cert-manager you can do Domain Validation and HTTP Validation. Based on the posted ClusterIssuer
you are doing HTTP Validation. So you need to make sure that secure.alexguedes.com
resolves to a globally available IP address and that Traefik port 443
is listening on that IP address.
