Hi there 👋

jenkins-docker-slave's Issues

it's time to upgrade to jdk8

From my testing, it seems that jdk7 is not compatible with jenkins 2.73.2 + docker plugin 1.0.2, maybe it's time to update to jkd 8?

Trying to use own Dockerfile fails

Hello,

I went through your blog on setting up docker slaves and got everything working great when I pull your image from https://hub.docker.com/r/bibinwilson/jenkins-slave/.

However, when creating my own Dockerimage following what you have in this repo, i cannot get Jenkins to connect to the slaves.

Here is my Dockerfile. Its almost identical to the one in this repo.

FROM ubuntu:18.04
LABEL maintainer="[email protected]>"
#needed for ansible install
ENV TZ=America/Chicago
RUN ln -snf /usr/share/zoneinfo/$TZ /etc/localtime && echo $TZ > /etc/timezone
RUN apt-get update && \
    apt-get -qy full-upgrade && \
    apt-get install -qy git && \
    apt-get install -qy openssh-server && \
    apt install -qy ansible &&\
    sed -i 's|session    required     pam_loginuid.so|session    optional     pam_loginuid.so|g' /etc/pam.d/sshd && \
    mkdir -p /var/run/sshd && \
    apt-get install -qy openjdk-8-jdk && \
    apt-get -qy autoremove && \
    useradd -ms /bin/bash jenkins && \
    echo "jenkins:jenkins" | chpasswd 
COPY .ssh/authorized_keys /home/jenkins/.ssh/authorized_keys
RUN chown -R jenkins:jenkins /home/jenkins/.ssh/
# Standard SSH port
EXPOSE 22
CMD ["/usr/sbin/sshd", "-D"]

I have a .ssh/authorized_keys directory/file with my Dockerfile and then run docker build -t ubuntu_ansible_slave:latest .

After updating Jenkins to use that Docker image, i begin getting authentication errors in jenkins logs. (assuming its failing to authenticate to the slave, but im not sure.)

I just dont understand why it works with your image, but wont with one built with an almost identical Dockerfile? What am i missing?

Any help would be greatly appreciated. Been bashing my head against the desk for far to long on this one.

Line 24 of the Docker file

ADD settings.xml /home/jenkins/.m2/

Thats where docker build bombs out for me. Can you explain where did settings.xml come from?

Thank you
