Do docker pull using jenkins - jenkins

Question

I would like to do next steps using jenkins:
1- docker pull <image_name>
2- docker run -i -t <command>
I´ve installed docker plugin on jenkins but is it this prossible? The documentations in docker plugin page is very poor .

Answer 1

These steps are executed programmatically by the plugin.
Alternatively you can execute an script into a jenkins slave with docker installed in build->execute shell:
#!/bin/bash
export image=`docker images httpd|wc -l`
echo image $image
if [ "$image" -lt "1" ];
then
docker pull httpd
fi
export container=`docker ps -all -f="name=webcontainer"|wc -l`
echo container $container
if [ "$container" -gt "1" ];
then
echo "Deleting webcontainer"
docker rm -f webcontainer
fi
BUILD_ID=dontKillMe docker run -d -t -p8888:80 --name webcontainer httpd
You can interact with created docker with below command:
`docker exec -it webcontainer /bin/bash`

Answer 2

These days (mid 2017, more than a year after the OP's question), you would use an inside directive of a Jenkins pipeline to pull and run within a docker image some commands.
For instance (Using Jenkins Pipelines with Docker), using the Docker Pipeline plugin:
docker.image('ruby:2.3.1').inside {
stage("Install Bundler") {
sh "gem install bundler --no-rdoc --no-ri"
}
stage("Use Bundler to install dependencies") {
sh "bundle install"
}
}
