FAQ

Why nodes/transports have hardcoded keys, ips and other inputs ? --------------------------------------------------------------

This is temporary situation, we will improve it in near future.

I want to use different SSH keys ----------------------------

Just update resource for example:

solar resource update ssh_transport1 '{"ssh_key": "/path/to/some/key"}'

I want to use passwords not keys

Just update resource:

solar resource update rsync1 '{"password": "vagrant", "key": null}'

Note

You need to change it for all transport resources (ssh and rsync by default).

How can I run solar celery worker ?

- If you use vagrant then you can just service solar-celery start|restart as vagrant user. - If you have gevent installed then you can use utils/solar-celery script. You may need to adjust log files etc. - You can spawn celery by hand too:

celery multi start 2 -A solar.orchestration.runner -P prefork -c:1 1 -c:2 2 -Q:1 scheduler,system_log -Q:2 celery

Note

We're currently working on removing celery completely.

How can I configure solar ?

There are several places where we search for config values:

1. .config file in CWD or in path from SOLAR_CONFIG env variable

2. if env SOLAR_CONFIG_OVERRIDE contains valid path then it override previous values 3. .config.override in CWD 4. You can also set upper-cased env variable which matches one of those in config

Why do you use celery with SQL backend instead of X ?

For simplicity, but nothing stops you from changing these defaults:

celery_broker: sqla+sqlite:////tmp/celery.db
celery_backend: db+sqlite:////tmp/celery.db

What database can I use with solar ?

By default for simplicity we use sqlite. On our vagrant environment we use single node riak. You can also use multiple nodes riak, with some strong consistent buckets.

Where can I find solar examples ?
