Run software probe in a Docker container

[yoursunny]

I figured out how to run the software probe inside a Docker container. I'm posting the procedure here in case it's useful for others.

1. Build the container image with this Dockerfile:

   FROM centos:8
   WORKDIR /root
   RUN echo 'assumeyes=1' >> /etc/yum.conf && \
       yum update && \
       yum install git tar rpm-build openssl-devel autoconf automake libtool make
   RUN git clone --recursive --depth=1 https://github.com/RIPE-NCC/ripe-atlas-software-probe.git && \
       ripe-atlas-software-probe/build-config/centos/bin/make-tars && \
       rpmbuild --bb rpmbuild/SPECS/atlasswprobe.spec && \
       mv rpmbuild/RPMS/x86_64/atlasswprobe-*.rpm ./ && \
       rm -rf ripe-atlas-software-probe rpmbuild
   RUN yum -y install atlasswprobe-*.rpm
   VOLUME /var/atlas-probe/etc
   WORKDIR /var/atlas-probe
   CMD ["/usr/local/atlas/bin/ATLAS"]
   

   Build command is:

   docker build -t atlas-probe .
   

2. Start the container with this command:

   docker run -d --name atlas-probe \
     --restart always \
     --cpus 0.03 --memory 64M \
     atlas-probe
   

3. View public key with this command:

   docker exec atlas-probe cat /var/atlas-probe/etc/probe_key.pub
   

4. To enable IPv6, follow this guide including the docker-ipv6nat step.

The probe connects, and can automatically reconnect using the same SSH key after the host machine reboots. There are a few errors in docker logs atlas-probe, but they seem to be harmless.

Command to build a container from RPM packages:

echo '
FROM centos:7
ADD https://ftp.ripe.net/ripe/atlas/software-probe/centos7/x86_64/atlasswprobe-5020-1.el7.x86_64.rpm /
RUN echo assumeyes=1 >> /etc/yum.conf && \
    yum update && \
    yum -y install /atlasswprobe-*.rpm && \
    rm -rf /var/cache/yum /atlasswprobe-*.rpm
VOLUME /var/atlas-probe/etc
WORKDIR /var/atlas-probe
CMD ["/usr/local/atlas/bin/ATLAS"]
' | docker build -t atlas-probe -
