I have the latest version of Jenkins Master 2.441 running inside a container using the image. I have also configured a Docker cloud using docker-plugin, version 1.5.

Starting from Jenkins 2.437, every time that I make a change to the Docker Agent templates and try to run a job, no new containers are created and the following comes up in the Jenkins Master logs:

Restarting the Jenkins Master preserves the new configuration and fixes the issue. New containers are spawned normally.

Starting from Jenkins 2.437, every time that I make a change to the Docker Agent templates and try to run a job, no new containers are created and the following comes up in the Jenkins Master logs:
{code:java}

Restarting the Jenkins Master preserves the new configuration and fixes the issue. New containers are spawned normally.

Here's a excerpt of my JCasC configuration for the docker-cloud plugin (logs above show what happened after editing the container template's entrypoint to remove the TUNNEL* variables):
{code:java}
clouds:
- docker:
dockerApi:
connectTimeout: 60
dockerHost:
uri: "tcp://socket-proxy:2375"
readTimeout: 60
name: "docker"
templates:
- connector:
jnlp:
entryPointArgumentsString: |-
^${TUNNEL_ARG}
^${TUNNEL}
-url
^${JENKINS_URL}
-secret
^${JNLP_SECRET}
-name
^${NODE_NAME}
jnlpLauncher:
webSocket: true
workDirSettings:
disabled: false
failIfWorkDirIsMissing: false
internalDir: "remoting"
user: "jenkins"
dockerTemplateBase:
cpuPeriod: 0
cpuQuota: 0
environment:
- "TZ=Pacific/Auckland"
environmentsString: |-
TZ=Pacific/Auckland
image: "<redacted>/jenkins-inbound-agent:jdk21_latest"
pullCredentialsId: "ecr:<redacted>"
instanceCapStr: "10"
labelString: "<redacted>"

pullTimeout: 600{code}
{{this.jnlpLauncher}} only appears to be referenced [here|https://github.com/jenkinsci/docker-plugin/blob/20f21b3c22a5af417ff20d054290feee696cfc55/src/main/java/io/jenkins/docker/connector/DockerComputerJNLPConnector.java#L61]. Looking at the Jenkins changelog, it could be related to [PR-8762|https://github.com/jenkinsci/jenkins/pull/8762] but I am not sure if that's the case.
