Using the Image

When creating the image in Exosphere, add a bootcmd to the advanced configuration, bootscript yaml. You need your ACCESS username (same one as on access.pegasus.isi.edu) and your token from access.pegasus.isi.edu:~/.condor/pilot.token. The /opt/ACCESS-Pegasus-Jetstream2/bin/vm-conf tool takes those two as argument. Leave the rest of the bootscript in place, like:

....
bootcmd:
  - /opt/ACCESS-Pegasus-Jetstream2/bin/vm-conf [username] [token]
runcmd:
....

Image Setup

Install this repo under /opt/ACCESS-Pegasus-Jetstream2 and create a salt symlink:

ln -s /opt/ACCESS-Pegasus-Jetstream2/salt /srv/salt

Then:

rpm --import https://repo.saltproject.io/py3/redhat/8/x86_64/latest/SALTSTACK-GPG-KEY.pub

curl -fsSL https://repo.saltproject.io/py3/redhat/8/x86_64/latest.repo >/etc/yum.repos.d/salt.repo

dnf install -y salt-minion

cat >/etc/salt/minion.d/50-main.conf <<EOF
