## TODO:
|
|
## - subordinate container should really be able to modify base image of their master
|
|
## - this could be done through docker-update
|
|
## - I'm not happy with the current build using 'build/' directory, this should be
|
|
## changed to:
|
|
## - always have a base image (specified in metadata), and always have hooks/install
|
|
## executed and merge in image (like docker-build-charm).
|
|
## - container base image is ALWAYS the image of the master container... this brings
|
|
## questions about a double way to express inheritage (through relations as it is
|
|
## implemented now, or through this base-image ?)
|
|
## - the name of the scripts for relation (aka relation_name-relation-joined) is bad as
|
|
## reading the name in a hooks/ dir, there are no way to know if we are the target or
|
|
## the base of the relation.
|
|
## - we could leverage a 'relations/' dir on the root of the charm, with both:
|
|
## 'relations/provide/relation_name' and 'relations/receive/relation_name'
|
|
## - a very bad point with the actual naming is that we can't have a providing AND
|
|
## receiving a relation with same name.
|
|
## - The cache system should keep md5 of docker-compose and other things between runs
|
|
## - The cache system should use underlying function that have only arguments inputs.
|
|
## This will allow to cache completely without issues function in time.
|
|
## - would probably need instrospection in charm custom action to know if these need
|
|
## init or relations to be set up.
|
|
## - Be clear about when the SERVICE name is used and the CHARM name is used.
|
|
## - in case of service contained in another container
|
|
## - in normal case
|
|
## - in docker-compose, can't use charm name: if we want 2 instances of the same charm
|
|
## we are stuck. What will be unique is the name of the service.
|
|
## - some relations are configured in compose.yml but should not trigger the loading
|
|
## of necessary component (for instance, apache --> log-rotate), if log-rotate is
|
|
## not there, this link should considered optional.
|
|
## - Could probably allow an unexistent charm to be populated with only "docker-image:"
|
|
## of the same name. Although this should trigger a visible warning.
