| It happens frequently not something constant, which makes it very hard to debug. This is my podTemplate:
podTemplate(containers: [
containerTemplate(
name: 'build',
image: 'my_builder:latest',
command: 'cat',
ttyEnabled: true,
workingDir: '/mnt/jenkins'
)
],
volumes: [
hostPathVolume(mountPath: '/var/run/docker.sock', hostPath: '/var/run/docker.sock'),
hostPathVolume(mountPath: '/mnt/jenkins', hostPath: '/mnt/jenkins')
],
yaml: """
spec:
containers:
- name: build
resources:
requests:
cpu: "10"
memory: "10Gi"
securityContext:
fsGroup: 995
"""
)
{
node(POD_LABEL) {
stage("Checkout") {
} // more stages
}
}
