withRegistry is not doing a "docker login"

Issue Type:	Bug
Assignee:	magnayn
Components:	docker-plugin
Created:	2017/Jan/12 10:39 PM
Environment:	Linux
Priority:	Major
Reporter:	David Karr

I have a block in my pipeline script like the following:

 
                                                                		docker.withRegistry("http://ourhost:5100", params.JP_DockerMechIdCredential) {
			def	image = docker.build("com.att.sharedservices/tomee-uslmonitor")
			image.push 'latest'
		}

Before this block of code, I extracted the username and password from the credential, and they are correct.

In the log, I watched it build the image, tag it, but then when it tried to push it, it failed to authenticate. I didn't see a "docker login" command line in the log.

I then tried to manually run the docker commands from the shell, on the same box the job is running on, starting with "docker login". That entire process worked.

I then reran my job, and it also worked.

I then moved my "~/.docker/config.json" file out of the way and reran my job, and it failed to authenticate again. It's just not attempting "docker login".

Re: withRegistry is not doing a "docker login"

Note that I was able to implement a workaround, with a modified block like this:

 
                                                                		withCredentials([[$class: 'UsernamePasswordMultiBinding', credentialsId: params.JP_DockerMechIdCredential, usernameVariable: 'USERNAME', passwordVariable: 'PASSWORD']]) {
			usr = USERNAME
			pswd = PASSWORD
		}
		docker.withRegistry("http://ourhost:5100", params.JP_DockerMechIdCredential) {
			sh "docker login -u ${usr} -p ${pswd} http://ourhost:5100"

			def	image = docker.build("com.att.sharedservices/tomee-uslmonitor")
			image.push 'latest'
		}

Re: withRegistry is not doing a "docker login"

I can also confirm that this worked!

I ended up using the following workaround:

 
                                                                // code placeholder
stage('Push image') {
/* Finally, we'll push the image with two tags:
* First, the incremental build number from Jenkins
* Second, the 'latest' tag. */
withCredentials([usernamePassword( credentialsId: 'docker-hub-credentials', usernameVariable: 'USERNAME', passwordVariable: 'PASSWORD')]) {

docker.withRegistry('', 'docker-hub-credentials') {
sh "docker login -u ${USERNAME} -p ${PASSWORD}"
myImage.push("${env.BUILD_NUMBER}")
myImage.push("latest")
}
