Docker containers keep restarting

[radtrentasei]

I have done a fresh install of netpalm but the containers do not stay UP.

(py3venv) [developer@devbox ~]$ docker ps

This is the error I am getting when running docker-compose not in background

netpalm-worker-fifo_1    | TypeError: To define root models, use `pydantic.RootModel` rather than a field called '__root__'

The problem is the pedantic version

In the requirement.txt most python module have no version or pinned down to a specific version:

requirements.txt
fastapi
ttp
netmiko==3.3.2
napalm
ncclient==0.6.9
requests
redis==4.5.1
rq
xmltodict
jinja2
jinja2schema
jsonschema
genie
pyyaml
cachelib==0.3.0
python-redis-lock
filelock
jsonpath_ng
apscheduler==3.6.3
puresnmp==1.9.1
pydantic
names_generator==0.1.0

That is bad practice and exactly causes such issues. The proper way to define requirement is to define a version range.
Here pedantic release a new major version 2.0 on 2023-06-30, the last version 1, v1.10.13 to be precise was released on 2023-09-27. The code was not adjusted to comply with the latest version and as no version was given in the requirements.txt the latest version is used and causes this issue.

if you change the line in the requirements.txt for the pydantic module, rebuilt the containers it works again.
pydantic>=1.10.13,<2.0

Usually all dependencies in requirements.txt should have a range from current to next major/minor release to get all security updates, but avoid problems with breaking changes between versions.

Pining down modules to specific version is also a bad idea as you miss out on all security updates.

Thanks, any chance we can integrate in the main repo?
I am happy to trigger the PR if needed.

Feel free to open PR and i will look to merge

I've stopped the PL because I've noticed that the containers are still reloading. This time I think the redis certificate has expired:

netpalm-controller_1     | redis.exceptions.ConnectionError: Error 1 connecting to redis:6379. [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: certificate has expired (_ssl.c:1131).

@tbotnz would you be able to help?

[empusas]

There is a script in the main directory of the repo called "redis_gen_new_certs.sh". Run the script, then rebuild the containers. It will work after that.
You can then include the new certificates in your PR.

I've been able to make them work and I've triggered the PR. Please review
