Add Debian - with the option of running a startup script and an option to copy /etc from the lab directory to the VM. Bind your /etc to /config/etc and your startup script to /config/startup.sh

Added these options using the backup script from the FreeBSD vm and used that also as a base for the startupscript and /etc option.

thanks @joolli !

do you mind checking if you can substitute this Dockerfile with the new version we started to use:

FROM ghcr.io/srl-labs/vrnetlab-base:0.2.1

ARG VERSION
ENV VERSION=${VERSION}
ARG IMAGE
COPY $IMAGE* /
COPY *.py /4
COPY backup.sh /
COPY copy_etc_and_run_startupscript.sh /

[joolli]

Do you want me to replace the whole Dockerfile? Will it be possible to resize the disk within the clab yaml?

I assume that "4" after "COPY *.py /" is a mistake.

I replaced the Dockerfile with yours and got:

Do I need a new launch.py as well?

[hellt]

I think you need to add another RUN command that installs cloud-utils

RUN apt-get update -qy \
   && apt-get install -y --no-install-recommends \
cloud-utils

[joolli]

If I only change the FROM statement to ghcr.io/srl-labs/vrnetlab-base:0.2.1, then it works. If you're happy with that, then I'll amend the pull request. Then the Dockerfile would look like this:

FROM ghcr.io/srl-labs/vrnetlab-base:0.2.1

ARG DISK_SIZE=4G

ARG DEBIAN_FRONTEND=noninteractive
RUN apt-get update -qy \
   && apt-get install -y \
   bridge-utils \
   iproute2 \
   socat \
   qemu-kvm \
   tcpdump \
   ssh \
   inetutils-ping \
   dnsutils \
   iptables \
   nftables \
   telnet \
   cloud-utils \
   sshpass \
   && rm -rf /var/lib/apt/lists/*

ARG VERSION
ENV VERSION=${VERSION}
ARG IMAGE
COPY $IMAGE* /
COPY *.py /
COPY backup.sh /
COPY copy_etc_and_run_startupscript.sh /

RUN qemu-img resize /${IMAGE} ${DISK_SIZE}

EXPOSE 22 5000 10000-10099
HEALTHCHECK CMD ["/healthcheck.py"]
ENTRYPOINT ["/launch.py"]

[hellt]

no need to keep everything. I think this should be fine:

FROM ghcr.io/srl-labs/vrnetlab-base:0.2.1

ARG DEBIAN_FRONTEND=noninteractive
RUN apt-get update -qy \
   && apt-get install -y --no-install-recommends \
   cloud-utils

ARG VERSION
ENV VERSION=${VERSION}
ARG IMAGE
COPY $IMAGE* /
COPY *.py /
COPY backup.sh /
COPY copy_etc_and_run_startupscript.sh /
