When deploying cert-manager using the Helm chart, we can specify the serviceAccount to use for:

the Webohook
the CA injector
the deployment
But we can't specify it for the HTTP01 ACME solver pod.

The problems with this are:

If the default serviceAccount is disabled, we need to provide a custom one
We can't use a serviceAccount with linked imagePullSecrets to be able to pull the solver image from private registries in air gapped environments
We can't apply PSPs to the solver pod.
To solve this, we propose to add a parameter --acme-http01-solver-service-account to cert-manager deployment to specify the serviceAccount to use in every namespace.

Hi @primael. Thanks for your PR.

I'm waiting for a jetstack or cert-manager member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

Hi,

As James mentioned in #3852, would it rather make more sense to have this as a field on the Issuer API instead of a flag?

primael added a commit to primael/cert-manager that referenced this pull request Apr 22, 2021
cert-manager create the HTTP01 ACME solver pod, when can specify:

The image: --acme-http01-solver-image
The serviceAccount (#cert-manager#3817): --acme-http01-solver-service-account
The resources
But we can't specify the imagePullSecret to use.

This is an issue for:

Air gapped environments with private registries
Docker Hub rate limits for anonymous pulls
It is currently possible to use the serviceAccount with an attached
imagePullSecret, but it is not always convenient because it requires to
update the serviceAccount of every namespace in the cluster to link the
imagePullsecret.
