@_slack_seleniumhq_U06440ZQPMZ:matrix.orgvietnd96 It will be out next hours 06:33:04
@_slack_seleniumhq_U06440ZQPMZ:matrix.orgvietnd96 Since want to include this fix from upstream just merged yesterday https://github.com/SeleniumHQ/selenium/pull/14282 06:35:00
@_slack_seleniumhq_U06440ZQPMZ:matrix.orgvietnd96 Also want to wait for Chromium v127, but seems it did not come on time 06:37:36

@_slack_seleniumhq_U070W6J5S07:matrix.orgEd Sherwin Nonog Hi everyone, why my parallel tests opens a multiple browsers to single session. However at the start of the test, it creates their individual session. 10:30:08
@_slack_seleniumhq_U06440ZQPMZ:matrix.orgvietnd96 Lets config 1 Node container to take 1 session at a time only SE_NODE_MAX_SESSIONS=1 10:39:54
@_slack_seleniumhq_U06440ZQPMZ:matrix.orgvietnd96 CLI opt would be --max-sessions by default, number of session detected by the number of processor available 10:42:13
@_slack_seleniumhq_U06440ZQPMZ:matrix.orgvietnd96 https://www.selenium.dev/documentation/grid/configuration/cli_options/#node 10:42:23
@_slack_seleniumhq_U070W6J5S07:matrix.orgEd Sherwin Nonog Thanks, I will check. Btw I am using k8s. Here's my current config. env: - name: SE_EVENT_BUS_HOST value: "selenium-hub" - name: SE_EVENT_BUS_SUBSCRIBE_PORT value: "4443" - name: SE_EVENT_BUS_PUBLISH_PORT value: "4442" - name: SE_SCREEN_WIDTH value: "2440" - name: SE_NODE_GRID_URL value: "http://10.0.0.0:4444" - name: SE_JAVA_OPTS value: "-Xmx8192m" - name: SE_SCREEN_HEIGHT value: "1440" - name: SE_SCREEN_DEPTH value: "24" - name: SE_NODE_PORT value: "5555" - name: SE_SESSION_REQUEST_TIMEOUT value: "900" - name: SE_SESSION_RETRY_INTERVAL value: "3" - name: SE_NODE_SESSION_TIMEOUT value: "6000" - name: SE_NODE_OVERRIDE_MAX_SESSIONS value: "false" - name: SE_VNC_NO_PASSWORD value: "1" - name: SE_VNC_VIEW_ONLY value: "1" - name: SE_NODE_MAX_SESSIONS value: "10" - name: SE_ENABLE_BROWSER_LEFTOVERS_CLEANUP value: "true" - name: SE_BROWSER_LEFTOVERS_INTERVAL_SECS value: "3600" - name: SE_BROWSER_LEFTOVERS_PROCESSES_SECS value: "7800" - name: "SE_DRAIN_AFTER_SESSION_COUNT" value: "10" - name: "SE_BROWSER_LEFTOVERS_TEMPFILES_DAYS" value: "1" resources: limits: cpu: "1" memory: "2000Mi" requests: cpu: ".5" memory: "1000Mi" affinity: nodeAffinity: requiredDuringSchedulingIgnoredDuringExecution: nodeSelectorTerms: - matchExpressions: - key: zone operator: In values: - testing 10:44:15
@_slack_seleniumhq_U06440ZQPMZ:matrix.orgvietnd96 so, it is - name: SE_NODE_MAX_SESSIONS value: "10" 10:45:52
@_slack_seleniumhq_U070W6J5S07:matrix.orgEd Sherwin Nonog but SE_NODE_MAX_SESSION=1 can trigger parallel tests? 10:47:56
@_slack_seleniumhq_U06440ZQPMZ:matrix.orgvietnd96 if K8s env, you can easy scale up the replicas to have multiple Node with mapping 1:1 kubectl scale deployment name --replicas=10 10:49:13
@_slack_seleniumhq_U070W6J5S07:matrix.orgEd Sherwin Nonog let me try that one. thank you 10:54:10
@_slack_seleniumhq_U063WPUSPCN:matrix.orgAmar Deep Singh Thanks for the info. No hurry from me. 11:51:52
@_slack_seleniumhq_U063WPUSPCN:matrix.orgAmar Deep Singh vietnd96 BTW where do you see those version list ? please share link if its publicly available. 12:05:32
@_slack_seleniumhq_U06440ZQPMZ:matrix.orgvietnd96 Via Nightly notes only https://github.com/SeleniumHQ/docker-selenium/releases/tag/nightly since we built images daily and audit deps version. So whenever the expected version comes, we can be aware 12:17:06

@_slack_seleniumhq_U068QC8MH6F:matrix.orgItseore Aleogena my chrome nodes have stopped registering w/ the hub. I'm running it on azure kubernetes w/ my own manifest files. I've attached the hub, chrome nodes and the loadbalancer service. As well as kubectl outputs and logs. If anyone wants to take a look i'd appreciate it. I have logs from a node trying to register, and logs from the hub.. as well as outputs of my deployments, pods and nodes 16:11:44
