I am trying to run the Docker images from gitlab-registry in Google Kubernetes Engine in a cluster and have traffic flow through ingress nginx controller. I am not able to achieve it. Here is the proper explanation. I build a pipeline using gitlab ci/cd and each time a pipeline is a success it pushes a docker image to gitlab registry. Now I want to test that images stored in the gitlab registry. I need to pull them and run containers from that images in the kubernetes cluster in Google Kubernetes Engine. I tried a lot of ways but a few errors keep coming. for example:/built_app/programs/server/node_modules/fibers/future.js:313 throw(ex); ^ MongoError: failed to connect to server [cluster1-shard-00-02-iqf6c.mongodb.net:27017] on first connect [MongoError: connection 5 to cluster1-shard-00-02-iqf6c.mongodb.net:27017 timed out] at Pool.<anonymous> (/built_app/programs/server/npm/node_modules/meteor/npm-mongo/node_modules/mongodb-core/lib/topologies/server.js:336:35) at emitOne (events.js:116:13) at Pool.emit (events.js:211:7) at Connection.<anonymous> (/built_app/programs/server/npm/node_modules/meteor/npm-mongo/node_modules/mongodb-core/lib/connection/pool.js:280:12) at Object.onceWrapper (events.js:317:30) at emitTwo (events.js:126:13) at Connection.emit (events.js:214:7) at TLSSocket.<anonymous> (/built_app/programs/server/npm/node_modules/meteor/npm-mongo/node_modules/mongodb-core/lib/connection/connection.js:199:10) at Object.onceWrapper (events.js:313:30)

I tried to set the environmental variables as a secret in the kubernetes cluster and used them. and also I created one more secret to use it for pulling images from the private gitlab registry.

I also have a Nginx-ingress-controller setup by the gitlab while integrated the kubernetes cluster with Gitlab.

I want to connect and test these docker images from the internet using the Ingress and the GKE. I am stuck here without any idea. Any help would be great for a beginner like me.

I have the kubernetes cluster integrated with gitlab CI and this integration have already installed some apps like ingress-nginx-controller, gitlab-runner and other on my cluster in GKE.

Here I am attaching the YAML files used in GKE.

apiVersion: apps/v1

these are the yaml fileS which I've been using. The mongodb which we use use is hosted on another service. The connection is not being made with mongoDB and I am stuck here. I am stuck and any help would be appreciated..
