Hi Cirulls,

I have just started working through your training videos and the course is great so far. I think i will have more confidence by the time i finish the training, but i am getting error message when i run the pipeline.

curl --user admin:admin -X POST -F "jenkinsfile=<Jenkinsfile" http://192.168.25.137:8080/pipeline-model-converter/validate
Errors encountered validating Jenkinsfile:
WorkflowScript: 25: Step does not take a single required parameter - use named parameters instead @ line 25, column 21.
steps { deploy('dev') }
^

WorkflowScript: 33: Step does not take a single required parameter - use named parameters instead @ line 33, column 21.
steps { deploy('stage') }
^

WorkflowScript: 45: Step does not take a single required parameter - use named parameters instead @ line 45, column 21.
steps { deploy('live') }

my version of jenkins is 2.190

As i am new to jenkins and using pipelines i am not sure how to edit the file to set named parameters to get rig of this error.

Can you help please?
Regards,
Vince bailey

When doing the CD Pipeline build in video 4.5 the Jenkinsfile_part_1 does not build properly.

Maybe I missed something in the videos, but I can't seem to get it running.

In the CI Workflow video, how exactly is http://localhost:9090 going to work if the docker container isn't configured to map that port to the same port on the host machine? Did you test your examples with a docker container?

The docker container does not include maven. The instructions in the video merely say

Before we get started with this video, make sure you have the following things set up, as we will not cover them during the demo. You may already have maven installed on your machine, but if not, the easiest way to install it is via Jenkins, by navigating to Manage Jenkins, Global Tool Configuration, Maven, and add the maven installation. Alternatively, you might want to install maven via your operating system.

I followed those instruction for installing maven via Jenkins adding the default installer (install from Apache), assuming that either maven must be a tool which could be installed by just unpacking files into an area in the file system to which the process/account running Jenkins had write access, or that Jenkins was running as root (a very unappealing thought). I was able to install maven by getting a root shell in the docker container (docker exec -it -u root ...) but the instructions as given in the video need to be adjusted. If it is indeed possible to install maven on the server from the Jenkins web interface, please provide more explicit instructions. Otherwise, explain the steps needed to get maven installed in the docker container without the assistance of Jenkins.

IN hands-on-jenkins/section_4/exercises/solutions.md it references to 4 files but they don't exist. Can you add those?

The text looks like this:
Practice
See the following files:

app.py
Jenkinsfile
test_flask_app.py
Jenkinsfile

First of all, good quality stuff, Sandro.

I run ubuntu host with Docker installed. As instructed in practical exercise I download Jenkins container image and run Jenkins from the container. It's all dandy but in chapter 4 when we need to build new images with docker build from Pipeline - Jenkins is not aware of any docker to build images

• docker build -t hands-on-jenkins/myapp:1 .
  /var/jenkins_home/workspace/proper-pipeline/section_4/code/cd_pipeline@tmp/durable-976ce4eb/script.sh: 1: /var/jenkins_home/workspace/proper-pipeline/section_4/code/cd_pipeline@tmp/durable-976ce4eb/script.sh: docker: not found

I created Jenkins container with "-v /var/run/docker.sock:/var/run/docker.sock" but that does not seam to help. As I understand installing docker inside Jenkins container - docker in docker is not a good approach either. So how can Jenkins in a container interact with my Ubuntu (host) Docker?
Am I missing something? Thanks for any tip.

Hello Sandro,

I followed your provided steps to install jenkins on docker. But when i access localhost:8080 and after I add the temporary admin password I get the message "This Jenkins instance appears to be offline." checking over google i get to know that my docker contain is not having the internet access (may be)

Can you help me resolve it?

lab setup:

1. I am using win10
2. Create a VM with centos in VMware workstation
3. Installed docker on it
4. Pull and run the jenkins/jenkins:lts

I noticed that under section_2/code there there is a helloworld_parameter.sh script. I was wondering if a similar file for windows can be added for folks using windows.

Hi Sandro,

When I build the pipeline using section_4/code/cd_pipleline/Jenkinsfiles_part_1, I get the following error. Please advise.

• docker ps -f name=app_dev -q
• xargs --no-run-if-empty docker stop
  xargs: illegal option -- -
  usage: xargs [-0opt] [-E eofstr] [-I replstr [-R replacements]] [-J replstr]
  [-L number] [-n number [-x]] [-P maxprocs] [-s size]
  [utility [argument ...]]

Thanks,
Azher

Hi, I have the next question, its possible add docker-compose in jenkins pipelines using jenkins container? how add docker-compose to jenkins container ? I try passing with volume similar to link docker.sock but i cant get the command docker-compose inside of my container.

PD: I learned much with packpub course and now i try to integrate jenkins in my projects hehehe
