Installing a fresh AZERO testnet node issues

[powerpsy]

When installing a new fresh node 13.1 on a new Ubuntu 22.04 server with docker configured as non root,

git clone https://github.com/Cardinal-Cryptography/aleph-node-runner
cd aleph-node-runner

You get the directory and script run_node.sh that will configure the node using the file in validator_testnet

1. For any reason, if you Ctrl+C during the snapshot phase, the script will not perform well at the end (I tried it twice and each time you end it with a restarting container)
2. For any reason, if you didn't correctly configure the env/validator_testnet BEFORE launching the script, the container will not be corrected. Example to reproduce:

• start the run_node.sh script until the end
• modify ports in the env/validator_testnet
• docker stop container
• start the run_node.sh script again
• You will get a container without the ports you changed. I tried this twice also.

In my case, I wrote "for any reason", to me the reason was that I was using a ssh session, I made the script via the ssh session whereas I wanted to start it directly from the server itself, so I Ctrl+C in the middle of the script from ssh before relaunching it directly on the server.

Good catch! Admittedly, we're not handling the interruptions during snapshot download very gracefully right now, will work on that
