RFC: Client/Server Configuration about luet HOT 6 CLOSED

Integrate support of Viper/Cobra configuration for both client and build packages commands.

Format supported is YAML (or viper supported format):

Example of a configuration for the client:

logging:
   path: /var/log/luet/luet.log
   level: "info"

general:
   concurrency: 4
   # debug: false

# Environment options are usable
proxy:
    http: xxx
    https: xxxx
    ftp: xxx

cache_repositories:

We should be consistent, and choose between underscore or dashes for naming (cache_repositories vs system-repositories). But my question is also, should we allow to define the cache per-repo for the user? or compute automatically the paths based on a root path (which is defined by the user?)

from luet.

The cache_repositories is intended like an L2 Cache where luet could retrieve packages/layers before use mirrors. I'm not sure that /var/cache/luet/repos is right here because could be the default path where fetch packages.

The idea is to use for example a directory where retrieve/store fetched files:

$# ls /var/cache/luet/repos/
repo1/pkg1.tar
repo2/pkg2.tar
...

Or in a LAN fetch packages from a node used as local cache mirrors that is integrated in this way:

1. Run: luet install pkg1
2. luet try to see if pkg1 is already present in local cache
3. if not present try to check if pkg is present on cached_repository with high priority
4. if pkg is not present try to fetch the package from URL defined inside repository object
5. if cached_repository has rw mode then try to push the package to cached_repos
6. luet install fetched package.

The cached repository could be a feature of API Server instances.

It seems that viper has an issue on parse structure from configuration files with field with an underscore (probably for the env key replacer):

$ ./luet config
 Using config file: /home/geaaru/go/src/github.com/mudler/luet/.luet.yaml
💣   [failed to load configuration: 1 error(s) decoding:

* 'cache_repositories[0]' expected a map, got 'string']🔥 
$ cat .luet.yaml
system_repositories:
   - name: "xxx"

I will rename system_repositories in repositories and cache_repositories in repetitors.

Just to trace the implemented configuration file: https://github.com/mudler/luet/blob/develop/contrib/config/luet.yaml

repetitors integration will be defined by a specific issue.
