Validate debug Dex token expiry before creating the TokenRequest
When ARGOCD_DEX_SERVER_TOKEN_EXPIRY_SECONDS is 0 or negative, getTokenExpirySeconds() returns it and getDexOAuthClientSecret() sends it to TokenRequestSpec.ExpirationSeconds. The Kubernetes API requires at least 600 seconds, so CreateToken can fail and propagate through Dex secret reconciliation instead of using the default. Reject values below the valid minimum and retain common.ArgoCDDexServerTokenExpirySecs on validation failure.

Set the default before invoking setEnvFunc.
Both current cases set setEnvFunc: nil, so this does not affect current cases. However, reconcileDexDeployment uses argoutil.IsDexEtcdStorageEnabled() to select the custom startup script and etcd sidecar. A case that enables this path through setEnvFunc would be reset to false by line 673.

Use the storage flag that Dex reads.
Line 221 sets ARGOCD_DEX_KUBERNETES_STORAGE_ENABLED, but argoutil.IsDexEtcdStorageEnabled() reads ARGOCD_DEX_ETCD_STORAGE_ENABLED and enables etcd when the value is unset. make start-e2e therefore starts etcd storage instead of disabling it. Set ARGOCD_DEX_ETCD_STORAGE_ENABLED="false".

Dex's storage.type enum is memory | kubernetes | etcd | sqlite3 | postgres | mysql. How about changing our feature flag to align with dex, something like: ARGOCD_DEX_STORAGE_TYPE = memory | kubernetes | etcd | sqlite3 | postgres | mysql, though we currently only need first 3.

Yes, that makes sense. It will help in future switch over where we can support additional configuration types.

Back the etcd data directory with durable storage. With Dex etcd storage enabled, the sidecar writes to /tmp/etcd-data under the default /tmp EmptyDir mount. A pod replacement, including a configuration-triggered Deployment rollout, removes this database and can invalidate Dex offline sessions and refresh tokens. Mount a PVC-backed volume at /tmp/etcd-data, or configure an equivalent durable data path.

Refresh copied TLS files when the mounted Secret changes.
The Dex Deployment accepts mounted volumes but has no TLS checksum, and reconciliation triggers rollouts only for configuration changes. If a mounted Secret updates, this script keeps using the initial /tmp/tls.crt and /tmp/tls.key, including after a configuration-only Dex restart. Compare the mounted files during polling, copy both files when either changes, and restart Dex.

Encrypt the Dex-to-etcd connection.
The generated Dex configuration and etcd sidecar both use plaintext HTTP. Configure the sidecar and Dex client for HTTPS or mTLS, mount the required certificates, and enable certificate validation.

In `@controllers/argoutil/dex.go` at line 24, Update the awkScriptEtcdStorageType
configuration so Dex connects to etcd over HTTPS or mTLS instead of plaintext
HTTP, and update the etcd sidecar configuration accordingly. Mount the required
CA and client certificates into both components, reference them in Dex’s etcd
settings, and enable certificate validation.

- Line 103: Update the etcd readiness retry loop in the bootstrap logic to track
whether a connection succeeds; after all 10 attempts fail, stop startup with a
nonzero exit status instead of proceeding to launch Dex, while preserving the
existing successful-connection path.

ARGOCD_DEX_ETCD_STORAGE_ENABLED is the old name and should be changed to the new one.

We could use some validation of the raw env var value.

can we make etcd an init container with restartPolicy: Always, to let kubernetes manage the lifecycle and ordering of etcd and dex containers? So etcd will starts before dex and shutdown after dex?

do we need to add the above http probes to dex networkpolicy to allow them? OCP will likely allow them but will be good for other platforms.

What does this PR do / why we need it:
Due to recent change for improving the security, dex service account tokens gets rotated every 1hour. When dex service account rotates, the dex config and the client secret changes, causing the existing logged in sessions to be invalidated. This causes existing logged-in users to be forced to re-login. The root cause of this issue is because Argo CD hard codes the storage to
memoryand there is no option provided to configure this specific field https://github.com/argoproj/argo-cd/blob/aa4629e50c2ae8c138b9333e4add48a7124d2aff/util/dex/config.go#L31To fix the issue, the signing keys needs to be stored in a persistent storage and dex provides the following options for persistent storage :
There is an upstream PR in argo-cd argoproj/argo-cd#28624 created to make this hardcoded storage setting to a configurable value. The PR is proposed as an enhancement and may not be available for back-porting. It may be available for 3.6 or 3.7 timelines based on when the PR would be accepted and merged. For bug fixes, this timelines and lack of backporting option makes this approach unacceptable, Due to the reason explained, a fix in the operator code is the preferred approach.
** Summary of changes done in this PR.
Subscriptionobject), use the etcd storageargocd-dex rundexwhich is valid for in-memory storage.rundexsubcommand, but the script provides a mechanism to change the storage config before the server is started.i. Create a self signed TLS certificate using
opensslcommand.ii. Generate the base Dex Config file using
argocd-dex gendexcfgiii. Use the
awkcommand to update the storage configuration in the generated base configuration and use that for the dex server.iv. Poll for any changes done to the dex config in
argocd-cmconfigmap. The poll interval is 15s. The change detection is done viagendexcfgcommand and comparing it with the previous configuration viasha256sum.v. When the SA token rotates, the dex config is modified and within 15s this change is detected and the process gets restarted via the TERM signal.
go build tagsto inject custom values for dex server token expiry and threshold. This is to improve the testing process and reduce the wait time to simulate and actual token rotation event. This code will be included only when the code is compiled with the-tag debugoption. Otherwise this custom code is not included in production images.Leaking go-routines is caused due to the process being handled within the go runtime.
rundexcommand uses internal go runtime'sos.Execcommand, which I suspect is not cleaning up some of the pending go-routines that could be left causing a leak. With a shell based approach, and passing the SIGTERM signal to the underlying dex server process directly, the cleanup of pending go-routines, must be addressed as well. This assumption needs to be verified and requires an environment where the issue can be reproduced.Have you updated the necessary documentation?
