A REST API in Kemal for interacting with DPPM https://dfabric.github.io/dppm-rest-api


Build Status Gitter ISC

REST API for DPPM, an installer/manager of server applications.




You will need a Crystal development environment.

You can either install it or use a Docker image.


Clone the repository and run:

shards build

The binary is bin/dppm

Run tests

This runs the formatter, the linter, then the spec tests:

crystal tool format && bin/ameba && crystal spec

Commands for setting permissions

The dppm server command has two subcommands for managing user permissions: user and group. This API uses a role-based access model. That is, a user itself does not have permissions, it is a member of a group (a role) which then has a defined set of permissions.

A user has three attributes -- a name, for referring to the user directly; an API key, for authentication; and a list of groups of which it is a member.

Editing users

For the edit, rekey, show, and delete commands, the users may be selected either by sepecifying a user's API key, if it is known, or by matching the name and groups the user is a member of. It is not recommended to match only by name or by groups, as your command may unintentionally affect similar users. For example, two users may choose the same name, but be members of different groups. This doesn't matter as they're only identified internally by their API keys, but you may unintentionally add/remove groups from those users when using this command in that situation.

Ideally, you won't have multiple users with the same name, or you can use the web interface to edit these values using API keys for exact identification.

This can also be used for batch processing. For example, if you want to replace one group with several more granular ones, you can add all members of the old group to the new groups before deleting the old group.

Matching on users

You may use an exact match like match-name=Scott, or by using regex, like match-name='/(D\..)?Scott.Boggs\d{0,2}/'. In either case, ANY matching user is selected, so again, if there are multiple users with the same name, they will all be selected.

Matching on groups

Group matches are non-exclusive -- that is, users may also be members of groups not specified, but they must be a member of the specified groups. You may specify several groups by separating them with commas, and multiple group selectors by separating them with a colon, like match-groups=1,2,3:2,4, which would select a user who's a member of groups 1, 2, and 3, or a user who's a member of groups 2 and 4.
