Change the default issuer for dex

[AnkitaBarbi]

I have just started working on dex , and have some concerns that I am unable to figure out

By default when we run dex issuer happens to be

issuer: http://127.0.0.1:5556/dex

but lets. say if I want the issuer to be registered with

issuer: https://abc.example.in

How do I achieve it?

Hello! You can change it via the dex configuration file.
There is an example of a config file https://github.com/dexidp/dex/blob/master/config.yaml.dist#L4

The issuer setting is what you are searching for.

hey @nabokihms I tried that and changed in config.yaml, and also change the same for example app main.go to test it. But then it throws below error

failed to query provider "https://abc.example.in": oidc: failed to decode provider discovery object: expected Content-Type = application/json, got "text/html; charset=utf-8": invalid character '<' looking for beginning of value

What am I missing?

I tested it locally using the current master branch.

1. Run commands to make binaries:

make bin/dex examples

2. Change issuer in examples/config-dev.yaml to http://abc.example.in:5556
3. Run dex:

bin/dex serve examples/config-dev.yaml

4. Run example app:

bin/example-app --issuer http://abc.example.in:5556

5. Login via the mock connector, inspect the received token:
