accessing files stored as secret files via the credentials plugin fails when running in a pipeline where only the particular stage is running in a docker container.
how to reproduce:
upload a file with the content "secret" via the credentials plugin:
credentials -> system -> global credentials -> add credentials -> secret file
access it via a pipeline which is containiserized on the top level:
#!groovy
pipeline {
agent {
docker {
label "worker"
image "alpine:3.8"
}
}
environment {
SECRET = credentials("secret")
}
stages {
stage("cat") {
steps {
sh "cat $SECRET"
}
}
}
}
this results in the expected log output:
[...] [project_master-IVL6IBXNKWVTPPV72MKSLBHB5K2X7C74P6THVIE7VGCZ2TT2GNOQ] Running shell script + cat **** secret [...]
access it via a pipeline where only a particular stage is containerized:
#!groovy
pipeline {
agent {label "worker"}
environment {
SECRET = credentials("secret")
}
stages {
stage("cat") {
agent {
docker {
label "worker"
image "alpine:3.8"
}
}
steps {
sh "cat $SECRET"
}
}
}
}
this results in the following error:
[...]
[project_master-IVL6IBXNKWVTPPV72MKSLBHB5K2X7C74P6THVIE7VGCZ2TT2GNOQ@2] Running shell script
+ cat ****
