.pkgr.yml to enable packaging on packager.io

[crohr]

This change enables packaging on Packager.io for the major linux distributions (see https://packager.io/gh/pkgr/kinto-heroku/build_runs/3 for an example build).

I tried to test the resulting package, but not sure what's going on after I set a proper DATABASE_URL:

Install the package:

$ wget -qO - https://deb.packager.io/key | sudo apt-key add -
$ echo "deb https://deb.packager.io/gh/pkgr/kinto-heroku trusty pkgr" | sudo tee /etc/apt/sources.list.d/kinto-heroku.list
$ sudo apt-get update
$ sudo apt-get install kinto

Setting a proper DATABASE_URL:

Can you tell what's wrong?

[Natim]

For the database URL you actually need to define multiple variables, see: https://github.com/Kinto/kinto/blob/master/docker-compose.yml#L12-L18

[Natim]

Ideally we wanted to create a /etc/kinto.ini file with the default configuration.

[crohr]

@Natim ok, what would be the default config? I can put that in a postinstall file

[Natim]

Ideally we should propose a production ready conf.

Having systemd managing a uwsgi daemon. You can have a first version of this configuration file (with most of the production settings as comments) by running kinto --ini ./kinto.ini --backend postgres init

[almet]

Oh, I missed this! Thanks for taking the time to do this @crohr.

You can generate a default configuration file by running kinto init. The resulting default file looks like that:

[server:main]
use = egg:waitress#main
host = 0.0.0.0
port = 8888


[app:main]
use = egg:kinto

# Backends.
# http://kinto.readthedocs.org/en/latest/configuration/settings.html#storage
kinto.storage_backend = cliquet.storage.postgresql
kinto.storage_url = postgres://postgres:postgres@localhost/postgres
kinto.cache_backend = cliquet.cache.postgresql
kinto.cache_url = postgres://postgres:postgres@localhost/postgres
kinto.permission_backend = cliquet.permission.postgresql
kinto.permission_url = postgres://postgres:postgres@localhost/postgres

kinto.userid_hmac_secret = 28460c66a3fc0e2644e7bdbb8c4ecfdc41455ed253ed63c4c8309b784aa7996a
multiauth.policies = basicauth

kinto.experimental_collection_schema_validation = true

kinto.includes = kinto.plugins.default_bucket

Let me know if you need any more help on this.

[Natim]

Any status update on this? I'd really like to have this feature.

[crohr]

@Natim I can have another look. However, do you know if the kinto.ini file can take environment variables instead of hard-coded values?

[Natim]

do you know if the kinto.ini file can take environment variables instead of hard-coded values?

Yes it can 👍

[Natim]

Should we update this PR or close it?

[crohr]

@Natim if you think having native packages still has value, then I'm available to help push this, otherwise I suppose you can close it. Let me know either way :)

[Natim]

I still think it can be interesting yes.
