- Be more explicit with exact instructions to startup
- Change some of the commands that were using local directory with "./" when
the executable was in a lower directory. These
commands (like "./bin/dex-worker") did not work on ZSH or Bash, so I
removed the leading "./"
- Add some syntax highlighting markdown to code sections

## No DB mode
|
|
|
|
When you are working on dex it's convenient to use the `--no-db` flag. This starts up dex in a mode which uses an in-memory datastore for persistence. It also does not rotate keys, so no overlord is required.
|
|
|
|
In this mode you provide the binary with paths to files for connectors, users, and emailer. There are example files you can use inside of `static/fixtures` named *"connectors.json.sample"*, *"users.json.sample"*, and *"emailer.json.sample"*, respectively.
|
|
|
|
You can rename these to the equivalent without the *".sample"* suffix since the defaults point to those locations:
|
|
|
|
```console
|
|
mv static/fixtures/connectors.json.sample static/fixtures/connectors.json
|
|
mv static/fixtures/users.json.sample static/fixtures/users.json
|
|
mv static/fixtures/emailer.json.sample static/fixtures/emailer.json
|
|
```
|
|
|
|
Starting dex is then as simple as:
|
|
|
|
```console
|
|
bin/dex-worker --no-db
|
|
```
|
|
|
|
***Do not use this flag in production*** - it's not thread safe and data is destroyed when the process dies. In addition, there is no key rotation.
|
|
|
|
Note: If you want to test out the registration flow, you need to enable that feature by passing `--enable-registration=true` as well.
|
|
|
|
## Building
|
|
|
|
To build using the go binary on your host, use the `./build` script.
|
|
|
|
You can also use a copy of `go` hosted inside a Docker container if you prefix your command with `go-docker`, as in: `./go-docker ./build`
|
|
|
|
## Docker Build and Push
|
|
|
|
Once binaries are compiled you can build and push a dex image to quay.io. Before doing this step binaries must be built above using one of the build tools.
|
|
|
|
```console
|
|
export DOCKER_USER=<<your user>>
|
|
export DOCKER_PASSWORD=<<your password>>
|
|
./build-docker-push
|
|
```
|
|
|
|
By default the script pushes to `quay.io/coreos/dex`; if you want to push to a different repository, override the `DOCKER_REGISTRY` and `DOCKER_REPO` environment variables.
|
|
|
|
## Rebuild API from JSON schema
|
|
|
|
Go API bindings are generated from a JSON Discovery file.
|
|
To regenerate run:
|
|
|
|
```console
|
|
schema/generator
|
|
```
|
|
|
|
For updating generator dependencies see docs in: `schema/generator_import.go`.
|
|
|
|
## Running Tests
|
|
|
|
To run all tests (except functional) use the `./test` script;
|
|
|
|
If you want to test a single package only, use `PKG=<pkgname> ./test`
|
|
|
|
The functional tests require a database; create a database (eg. `createdb dex_func_test`) and then pass it as an environment variable to the functional test script, eg. `DEX_TEST_DSN=postgres://localhost/dex_func_test?sslmode=disable ./test-functional`
|
|
|
|
To run these tests with Docker is a little trickier; you need to have a container running Postgres, and then you need to link that container to the container running your tests:
|
|
|
|
|
|
```console
|
|
# Run the Postgres docker container, which creates a db called "postgres"
|
|
docker run --name dex_postgres -d postgres
|
|
|
|
# The host name in the DSN is "postgres"; that works because that is what we
|
|
# will alias the link as, which causes Docker to modify /etc/hosts with a "postgres"
|
|
# entry.
|
|
export DEX_TEST_DSN=postgres://postgres@postgres/postgres?sslmode=disable
|
|
|
|
# Run the test container, linking it to the Postgres container.
|
|
DOCKER_LINKS=dex_postgres:postgres DOCKER_ENV=DEX_TEST_DSN ./go-docker ./test-functional docker
|
|
|
|
# Remove the container after the tests are run.
|
|
rm -f dex_postgres
|
|
```
