Jose Diaz-Gonzalez	97b9b9582f	fix: drop now unnecessary rm call in config This was used to delete an errant '*' service that was accidentally created during service deletion. That was fixed in dokku/dokku-redis#126 - and the respective PRs for each service - and is thus no longer necessary. The fix was done by utilizing pushd when iterating over folders instead of trying to get a subdirectory with a partially quoted path. Closes dokku/dokku-redis#130	2019-06-08 15:53:54 +02:00

Jose Diaz-Gonzalez	1551ec61e7	fix: Strictly validate service names We previously allowed a wide range of service names. As the service name is sometimes used to name databases, the name was actually more restricted than any character, resulting in services that wouldn't start. Going forward, only alphanumeric and underscore characters are allowed. This only impacts service creation. Any services with invalid names should be migrated to a new service, with the data exported and imported as normal.
