Jenkins pipeline fails to login to docker hub - docker

Question

I am trying to use pipeline to run a few things and when i started running my pipeline it failed to login to docker.
the weird thing is that i am able to login on the machine itself but when i run the pipeline is fails with this weird error:
Started by user admin
Running in Durability level: MAX_SURVIVABILITY
[Pipeline] Start of Pipeline
[Pipeline] stage
[Pipeline] { (Front-end)
[Pipeline] node
Running on test-env in /var/www/test-env/workspace/client-e2e

[Pipeline] {
[Pipeline] withDockerRegistry

[Pipeline] }
[Pipeline] // withEnv
[Pipeline] }
[Pipeline] // node
[Pipeline] }
[Pipeline] // stage
[Pipeline] End of Pipeline
ERROR: docker login failed
Finished: FAILURE
I don't know why it performs a login when this image is publicly available for everyone.
can someone help me ?
this is the pipeline itself:
pipeline {
agent none
stages {
stage('Front-end') {
agent {
docker {
image 'node:8-alpine'
label "test-env"
}
}
steps {
sh 'node --version'
}
}
}
}

Answer 1

You can try with Credentials Binding Plugin in:
steps {
sh 'node --version'
}
You can do:
withCredentials([string(credentialsId: 'mytoken', variable: 'TOKEN')]) {
sh '''
docker login -u '<your_user>' -p '<$TOKEN>'
node --version
'''
}
There is an example here:

Answer 2

Ok, so after a while i found out that it was as simple as doing this
pipeline {
agent none
stages {
stage('Front-end') {
agent {
docker {
image 'node:8-alpine'
registryUrl 'https://index.docker.io/v1/'
label "test-env"
}
}
steps {
sh 'node --version'
}
}
}
}
this was aded: registryUrl 'https://index.docker.io/v1/'
