My pods are getting created but some build are failing with an error similar to the following in the console output or controller logs:
java.net.SocketTimeoutException: connect timed out at java.net.PlainSocketImpl.socketConnect(Native Method) at java.net.AbstractPlainSocketImpl.doConnect(AbstractPlainSocketImpl.java:350) at java.net.AbstractPlainSocketImpl.connectToAddress(AbstractPlainSocketImpl.java:206) at java.net.AbstractPlainSocketImpl.connect(AbstractPlainSocketImpl.java:188) at java.net.SocksSocketImpl.connect(SocksSocketImpl.java:392) at java.net.Socket.connect(Socket.java:589) at okhttp3.internal.platform.Platform.connectSocket(Platform.java:129) at okhttp3.internal.connection.RealConnection.connectSocket(RealConnection.java:246) at okhttp3.internal.connection.RealConnection.connect(RealConnection.java:166) [...]
java.net.SocketTimeoutException: connect timed out is caused by the connection timeout being exceeded during the connection between the Jenkins controller and a kubernetes agent. This timeout applies after the connection has been established. It is set to
5s by the kubernetes plugin by default.
Before Kubernetes plugin version 1.22.3, a value of
0 results in a Connection Timeout of
10s: no timeout is explicitly set to the kubernetes client and the default timeout of the
okhttp client is used.
Since Kubernetes plugin version 1.22.3, the minimum value possible for the Connection Timeout is
If an instance is impacted by this problem, consider increasing the Connection Timeout in the Kubernetes Cloud configuration.
|An issue in the kubernetes plugin prior to version 1.14.9 prevents from persisting the configured value of the connection timeout. The kubernetes plugin must first be upgraded to version 1.14.9 or later (CloudBees Core 126.96.36.199 or later).|
CloudBees Core on Modern Platform
If using CloudBees Core on Modern Platform, this can be done from the Operations Center.
In the Operations Center, select the "All" view and configure the item "kubernetes shared cloud". Then adjust the value of the Connection Timeout. Once saved, it may take a few seconds for the change to be applied to all managed controllers.
Go toand adjust the Connection Timeout of the Kubernetes cloud configuration.
