* Fixed possible constraint violation with an existed organization.
Usecase is following:
If we have already an organization with name, let's say "org" and the new user also has name "org" then we will have constraint violation.
In this case, we will try to create the user with name "org"+random string.
Multi-user Eclipse Che (#6441)
#### How to run it.
```docker run -it -e CHE_MULTIUSER=true -e CHE_HOST=<your ip> -e CHE_KEYCLOAK_AUTH-SERVER-URL=http://<your ip>:5050/auth -v /var/run/docker.sock:/var/run/docker.sock -v ~/.che-multiuser:/data eclipse/che:nightly start --skip:pull --skip:nightly```
#### How to manage it
- Keycloak configured with two realms. ```Master``` and ```che```. Also we have one user admin/admin in both realm. Admin user in master realm is - super admin.
- Eclipse Che configured for che realm
- We enabled user registration in ```Che``` realm
#### Known limitation
- swagger would not work. We need to upgrade a version. to support openid authentification https://github.com/eclipse/che/issues/6015
- It's working on local docker. We are going to provide scalable version based on OpenShift on next versions.
- Invitation of non-existent users to Eclipse Che organization https://github.com/eclipse/che/issues/6335
#### How to run it when it is in a branch
To run an multiuser Che version, the following steps are required after building the branch:
- Rebuild init, cli and che images (in the given sequence). To do that, proceed to folder _dockerfiles/<image_name>_ and run _build.sh_
- Run Che in a usual way using cli, with additional parameters: `-e CHE_MULTIUSER=true` and `--skip:pull --skip:nightly`
Full command example:
`docker run -it --rm -v /var/run/docker.sock:/var/run/docker.sock -v /home/user/.che:/data -e CHE_MULTIUSER=true eclipse/che-cli:nightly start --skip:pull --skip:nightly`
- MacOS users may need to edit _che.env_ file in the data folder, changing `CHE_HOST` and `CHE_KEYCLOAK_AUTH__SERVER__URL` values to their specific IP.
When start is succeeded, the following docker containers should be created:
- che, exposing 8080 port;
- che_keycloak, exposing 5050 port;
- che_postgres, exposing 5432 port;
It is needed since it is secured by permissions system which requires
an authenticated user.
Also, use base API endpoint for checking Che in OpenShift deploy
script since system state API which was used before is secured now.
