Deploying n8n on GKE via Terraform yields session drops from Ingress. How can I enforce session stickiness or adopt a different ingress strategy?
resource "my_cert" "betaTLS" {
name = "release-beta-tls"
domains = ["n8n.sample.org"]
}
resource "my_ingress" "betaRoute" {
service_selector = "n8n-service"
port = 8080
annotations = { "session-affinity": "true" }
}
I have encountered similar issues when deploying web applications on GKE. In my experience, relying solely on the ingress annotation for session affinity is sometimes not enough, especially if the load balancing settings do not fully support sticky sessions. I resolved the session drop problem by adjusting the service configuration on the backend as well, making sure the target service was correctly set up for persistent sessions. I also encountered that incorporating Google’s backendConfig for tuning load balancing parameters made a significant difference. I would recommend checking if these backend configurations align with the latest GKE recommendations to maintain session consistency.
Based on my experience, using simple annotations may not always achieve the desired sticky session behavior in a GKE environment. I transitioned to an approach where I configured the GKE HTTP(S) load balancer directly through backend services, ensuring that session affinity settings were applied at both the ingress and service level. This method provided more reliable session persistence and allowed detailed customization of load balancing parameters. Consolidating settings across both layers reduces inconsistencies. I recommend reviewing the latest documentation for backendConfig integration, as adjustments there significantly mitigated session drops in my deployments.
hey i had a simlar issue before. i ended up tweaking cookie stickyness on both my ingress and service configs. small mismatches in health-checks can mess things up. maybe double-check that both levels align for a proper fix. good luck!
Based on my experience with configuring n8n deployments in GKE, I encountered issues where session stickiness didn’t work as expected until I carefully aligned both ingress and service configurations. I learned that besides adding annotations for session affinity, it is critical to match parameters like timeouts and health check intervals between the ingress and the backend service. I experienced that minor discrepancies in these settings can cause routing inconsistencies resulting in dropped sessions. A detailed review of the documentation for updated load balancing configurations in GCP provided further clarity and helped refine the solution.
In my experience deploying n8n on GKE using Terraform, I found that ensuring consistency in session stickiness required more than applying default ingress annotations. I addressed this by setting a custom cookie name in the backend configuration, making sure that both the ingress and the service explicitly referenced the same cookie parameter. Additionally, I verified that the health checks and timeout settings were harmonized across the board. This approach, focusing on cookie-based affinity and consistent backend settings, led to a notable reduction in session drops in my deployments.
