dex

Dex is an identity service that uses OpenID Connect to drive authentication for other apps. Dex acts as a portal to other identity providers through "connectors." See documentation

Type of Package

Service package

Use as Dependency

Service packages can be set as runtime (as well as build time) dependencies. See Defining your dependencies for more information.

To add core/dex as a runtime dependency, you can add the following to your plan file.

pkg_deps=(core/dex)

If for some reason, this package is only needed as a build time dependency then do not include it in pkg_deps, but only in pkg_build_deps:

pkg_build_deps=(core/dex)

Using dex as a habitat service

Simple usage from a hab studio:

$ # build and install dex
$ build .
$ source ./results/last_build.env
$ hab pkg install ./results/$pkg_artifact
$
$ # export and run as a docker container
$ hab pkg install core/docker core/hab-pkg-export-docker
$ hab pkg export docker ./results/$pkg_artifact
$ hab pkg exec core/docker docker run --name core_dex -p 9000:9000 --rm -de HAB_LICENSE=accept core/dex

Further development of the dex plan

The hab studio provides an excellent way to further develop and or troubleshoot the dex hab service. Since dex provides an http endpoint on port 5556, then enter a hab studio with the following command.

HAB_DOCKER_OPTS="-p 5556:5556" hab studio enter -D

Once in the studio, then build and load the service:

build .
source ./results/last_build.env
hab pkg install ./results/$pkg_artifact
hab svc load $pkg_ident

Verify the http endpoint, e.g., open a browser at http://localhost:5556/

For example:

# build dex
[21][default:/src/dex:0]# build .
building artifact
...
...
'/hab/cache/artifacts/core-dex-2.24.0-20200826103442-x86_64-linux.hart' -> '/src/dex/results/core-dex-2.24.0-20200826103442-x86_64-linux.hart'
