Fabric8 Auth

1. Documentation

You can find both reference documentation and developer documentation in the following location:

2. Building from source

The following guide is mainly targeted towards a Linux or Mac OSX development machine. If you are on Windows, we recommend to take a look at Getting started with fabric8-auth development on Windows.

2.1. Prerequisites

You need to install:

  • go (>= v1.8)

  • git

  • mercurial

  • make

2.1.1. Check your Go version

Run the following command to find out your Go version.

$ go version

You must at least have Go version 1.8.

See Fetch dependencies to see an explanaition on how we deal with dependencies.

2.1.2. Install dep

This project uses dep as a package manager for Go. Running the make deps command will install dep in $GOPATH/bin if it’s not already available on your system.

2.2. Get the code

Assuming you have Go installed and configured (have $GOPATH setup) here is how to build.

Check out the code

$ git clone https://github.com/fabric8-services/fabric8-auth $GOPATH/src/github.com/fabric8-services/fabric8-auth

2.3. Build

Like most other projects, this one depends on various other projects that need to be downloaded.

We also generate some code from design files that shall make it into our final artifacts.

To fetch the dependencies, generate code and finally build the project you can type make in a freshly clone repository of this project.

$ cd $GOPATH/src/github.com/fabric8-services/fabric8-auth
$ make

If you are getting the following error

[ERROR]	Failed to set references: Unable to update checked out version (Skip to cleanup)
make: *** [vendor] Error 1

Try out this

$ glide cache-clear
$ make clean deps
$ make build

2.3.1. Special make targets

There is no need to fetch the dependencies, or re-generate code every time you want to compile. That’s why we offer special make targets for these topics:

Fetch dependencies

This will download all the dependencies for this project inside a directory called vendor. This way we can ensure that every developer and our CI system is using the same version.

$ cd $GOPATH/src/github.com/fabric8-services/fabric8-auth
$ make deps

For dependency management of go packages we use dep.

The file Gopkg.toml contains all dependencies. If you want to understand the format for this file, look here.

Generate GOA sources

You need to run this command if you just checked out the code and later if you’ve modified the designs.

$ cd $GOPATH/src/github.com/fabric8-services/fabric8-auth
$ make generate
Build

If you want to just build the Auth server and client, run make build.

$ cd $GOPATH/src/github.com/fabric8-services/fabric8-auth
$ make build
Clean

This removes all downloaded dependencies, all generated code and compiled artifacts.

$ cd $GOPATH/src/github.com/fabric8-services/fabric8-auth
$ make clean
Tests

Here’s how to run all available tests. All tests will check all Go packages except those in the vendor/ directory. Make sure you have docker and docker-compose available.

Setting up test environment - make integration-test-env-prepare

Tear test environment down - make integration-test-env-tear-down

unit-tests

Unit tests have the minimum requirement on time and environment setup.

$ cd $GOPATH/src/github.com/fabric8-services/fabric8-auth
$ make test-unit
integration-tests

Integration tests demand more setup (i.e. the PostgreSQL DB must be already running) and probably time. We recommend that you use docker-compose up -d db.

$ cd $GOPATH/src/github.com/fabric8-services/fabric8-auth
$ make test-integration
e2e-tests

End-to-End tests uses DB (i.e. the PostgreSQL DB must be already running). We recommend that you use docker-compose up -d db.

$ cd $GOPATH/src/github.com/fabric8-services/fabric8-auth
$ make test-e2e
all

To run both, the unit and the integration tests you can run

$ cd $GOPATH/src/github.com/fabric8-services/fabric8-auth
$ make test-all

By default, test data is removed from the database after each test, unless the AUTH_CLEAN_TEST_DATA environment variable is set to false. This can be particularily useful to run queries on the test data after a test failure, in order to understand why the result did not match the expectations.

Also, all SQL queries can be displayed in the output if the AUTH_ENABLE_DB_LOGS environment variable is set to `true. Beware that this can be very verbose, though ;)

Coverage

To visualize the coverage of unit, integration, or all tests you can run these commands:

  • $ make coverage-unit

  • $ make coverage-integration

  • $ make coverage-all

Note
If the tests (see Tests) have not yet run, or if the sources have changed since the last time the tests ran, they will be re-run to produce up to date coverage profiles.

Each of the above tests (see Tests) produces a coverage profile by default. Those coverage files are available under

tmp/coverage/<package>/coverage.<test>.mode-<mode>

Here’s how the <placeholders> expand

<package>

something like github.com/fabric8-services/fabric8-auth/models

<test>

unit or integration

<mode>

Sets the mode for coverage analysis for the packages being tested. Possible values for <mode> are set (the default), count, or atomic and they directly relate to the output of go test --help.

  • set: bool: does this statement run?

  • count: int: how many times does this statement run?

  • atomic: int: count, but correct in multithreaded tests; significantly more expensive.

In addition to all individual coverage information for each package, we also create three more files:

tmp/coverage.unit.mode-<mode>

This file collects all the coverage profiles for all unit tests.

tmp/coverage.integration.mode-<mode>

This file collects all the coverage profiles for all integration tests.

tmp/coverage.mode-<mode>

This file is the merge result of the two afore mentioned files and thus gives coverage information for all tests.

2.3.2. Development

These files and directories are generated and should not be edited:

  • ./app/

  • ./client/

  • ./swagger/

  • ./tool/cli/

3. Developer setup

Start up dependent docker services using docker-compose and runs auto reload on source change tool fresh.

$ cd $GOPATH/src/github.com/fabric8-services/fabric8-auth
$ make dev

The above steps start the API Server on port 8089.

Test out the build by executing CLI commands in a different terminal.

Note
The CLI needs the API Server which was started on executing make dev to be up and running. Please do not kill the process. Alternatively if you haven’t run make dev you could just start the server by running ./bin/auth.

Generate a token for future use.

./bin/auth-cli generate token -H localhost:8089 --pp

You should get Token in response, save this token in your favourite editor as you need to use this token for POST API calls

3.1. Creating User using Service Account token in DB.

3.1.1. Creating Service Account token for online registration.

We need Service Account token to create user in AUTH. Now to create SA token in development mode, we can use following api

curl -X POST http://localhost:8089/api/token -H 'Content-Type: application/json' -d '{
  "client_id": "f867ec72-3171-4b8f-8eec-90a32eab6e0b",
  "client_secret": "secret",
  "grant_type": "client_credentials"
}'

You will receive response like follow:

{"access_token":"eyJhbGciOiJSUzI1NiIsImtpZCI6IjlNTG5WaWFSa2hWajFHVDlrcFdVa3dISXdVRC13WmZVeFItM0Nwa0UtWHMiLCJ0eXAiOiJKV1QifQ.eyJpYXQiOjE1Mzg2NTYwMTYsImlzcyI6Imh0dHA6Ly9sb2NhbGhvc3QiLCJqdGkiOiI0MjA1NGE4MS1jNjdlLTQ0MGQtYjQ1My1kNzkwNmM3ZjE5MDQiLCJzY29wZXMiOlsidW1hX3Byb3RlY3Rpb24iXSwic2VydmljZV9hY2NvdW50bmFtZSI6Im9ubGluZS1yZWdpc3RyYXRpb24iLCJzdWIiOiJmODY3ZWM3Mi0zMTcxLTRiOGYtOGVlYy05MGEzMmVhYjZlMGIifQ.esAmoXFhkHq02-ABf22FHZtO7ytfNzmMHPoAYwsDYYVQ5thPyXPNTWXnhHu4bV0rACnf7R5oa3oIl14DhyPSTMjAN_qZZlWQC2qjhMEOBSbss_hW5BkYwU67YBhkHt_eYgfVuoAgi7SuMu5KucaBIMNBEpYrDXR6G9Q2qk3jq4tV4qbTaQ6P078pdfYKT2ue_eGbSEvUN4G33tTzI-TX6UrR3mi-jsavLkRGAPUZmvdIVigHMi-KM1oilw7IB24FB6rd4AMuD1OVhgV-r9qrA3MDdLP6mS_t09D30ROAoymJEy44OvbmdVo0XAQRD6_JyzHhK-YrAGN-39C5BDBeFw",
 "token_type":"Bearer"
}

3.1.2. Approving User in Auth DB and Creating user in WIT

Once you have RHD account and auth service running locally, you can use above created service account token to create user like following

curl -X POST  http://localhost:8089/api/users   -H "authorization: Bearer $SERVICE_ACCOUNT_TOKEN"   -H 'content-type: application/json'   -d '{
  "data": {
    "attributes": {
      "email": "[email protected]",
      "rhd_username": "dipakpawar",
      "username": "dipakpawar",
      "cluster": "https://cluster-url.com",
      "rhd_user_id":"3383826c-51e4-401b-9ccd-b898f7e2397d"
    },
    "type": "identities"
  }
}'

You don’t have to find rhd_user_id from RHD as it is random UUID and you can put any random number there.

This will create identity and user in the auth DB and user in WIT. Make sure to give correct email and username with your identity provider(RHD).

Note: If you haven’t not created user, you will get user dipakpawar is not approved error during logging. You need to follow above mentioned steps to approve user.

3.1.3. Running above steps using shell script

If you are too lazy to do above steps just run following command with your server, username, email parameters.

 curl -sSL https://git.io/fxY5T | bash -s -- -s http://localhost:8089/api/token -u username -e email  -c mycluster.url.com

3.2. Reset Database

The database are kept in a docker container that gets reused between restarts. Thus restarts will not clear out the database.

To clear out the database kill the database like this:

$ docker kill fabric8auth_db_1 && docker rm fabric8auth_db_1

In case you have mulitple fabric8* running use docker ps to locate the container name.
