Hi guys, I'm trying to use Docker cloud and I have 2 questions:
1) How can I debug the spawned docker agent container? I've found that by setting the "Docker Command" field in "Docker Agent Templates" > "Container Settings" I can have the container stopped but not removed. FTR I've put in this field: "docker run -v /var/run/docker.sock:/var/run/docker.sock xwiki/xwiki-jenkins-slave" However, what's strange is that I see in the job logs that the Jenkins workspace is located in /root/workspace (/root being the home dir of the root user), but when I start the stopped container with "docker start", there's nothing in /root Is there some volume binding happening? I was also expecting "docker start" to restart any volume binding. 2) In my logs, I can see that I've set JAVA_HOME properly but when maven installs and starts it says it's not set: ➡ JAVA_HOME: /home/hudsonagent/java8[Pipeline] echo <https://ci.xwiki.org/view/All/job/VincentDockerTest/43/console#>➡ Using Maven tool: Maven[Pipeline] echo <https://ci.xwiki.org/view/All/job/VincentDockerTest/43/console#>➡ Using Maven options: -Xmx2048m -Xms512m[Pipeline] echo <https://ci.xwiki.org/view/All/job/VincentDockerTest/43/console#>➡ Artifact archiving: false[Pipeline] echo <https://ci.xwiki.org/view/All/job/VincentDockerTest/43/console#>➡ Dependencies fingerprinting: false[Pipeline] withMaven <https://ci.xwiki.org/view/All/job/VincentDockerTest/43/console#>[withMaven] Options: [org.jenkinsci.plugins.pipeline.maven.publishers.GeneratedArtifactsPublisher[disabled=true], org.jenkinsci.plugins.pipeline.maven.publishers.DependenciesFingerprintPublisher[disabled=true, scopes=[compile, provided, runtime], versions={snapshot:true, release:false}]] [withMaven] Available options: [withMaven] using JDK installation provided by the build agent Unpacking https://repo.maven.apache.org/maven2/org/apache/maven/apache-maven/3.5.4/apache-maven-3.5.4-bin.zip to /root/tools/hudson.tasks.Maven_MavenInstallation/Maven on Jenkins SSH Slave-000bzx6dkvokq on docker [withMaven] using Maven installation 'Maven'[Pipeline] { <https://ci.xwiki.org/view/All/job/VincentDockerTest/43/console#>[Pipeline] echo <https://ci.xwiki.org/view/All/job/VincentDockerTest/43/console#>➡ Using Maven goals: clean verify[Pipeline] echo <https://ci.xwiki.org/view/All/job/VincentDockerTest/43/console#>➡ Using Maven profiles: docker,integration-tests [Pipeline] echo <https://ci.xwiki.org/view/All/job/VincentDockerTest/43/console#>➡ Using Maven properties: [Pipeline] echo <https://ci.xwiki.org/view/All/job/VincentDockerTest/43/console#>➡ Using timeout: 240[Pipeline] echo <https://ci.xwiki.org/view/All/job/VincentDockerTest/43/console#>➡ Java version used:[Pipeline] sh <https://ci.xwiki.org/view/All/job/VincentDockerTest/43/console#>+ java -version Picked up JAVA_TOOL_OPTIONS: -Dmaven.ext.class.path="/root/workspace/VincentDockerTest/master@tmp/withMavenf241505a/pipeline-maven-spy.jar" -Dorg.jenkinsci.plugins.pipeline.maven.reportsFolder="/root/workspace/VincentDockerTest/master@tmp/withMavenf241505a" openjdk version "1.8.0_202" OpenJDK Runtime Environment Corretto-8.202.08.2 (build 1.8.0_202-b08) OpenJDK 64-Bit Server VM Corretto-8.202.08.2 (build 25.202-b08, mixed mode)[Pipeline] echo <https://ci.xwiki.org/view/All/job/VincentDockerTest/43/console#>➡ Current user:[Pipeline] sh <https://ci.xwiki.org/view/All/job/VincentDockerTest/43/console#> + whoami root[Pipeline] timeout <https://ci.xwiki.org/view/All/job/VincentDockerTest/43/console#>Timeout set to expire in 4 hr 0 min[Pipeline] { <https://ci.xwiki.org/view/All/job/VincentDockerTest/43/console#>[Pipeline] echo <https://ci.xwiki.org/view/All/job/VincentDockerTest/43/console#>➡ Using POM file: pom.xml[Pipeline] sh <https://ci.xwiki.org/view/All/job/VincentDockerTest/43/console#>+ mvn -f pom.xml clean verify -Pdocker,integration-tests --projects org.xwiki.platform:xwiki-platform-menu-test-docker -Dmaven.test.failure.ignore ----- withMaven Wrapper script ----- The JAVA_HOME environment variable is not defined correctly This environment variable is needed to run this program NB: JAVA_HOME should point to a JDK not a JRE[Pipeline] }[Pipeline] // timeout[Pipeline] }[Pipeline] // withMaven Any idea?
