# cc-docker
|
|
|
|
This is a `docker-compose` setup which provides a quickly started environment for ClusterCockpit development and testing, using `cc-backend`.
|
|
A number of services is readily available as docker container (nats, cc-metric-store, InfluxDB, LDAP), or easily added by manual configuration (MySQL).
|
|
|
|
It includes the following containers:
|
|
* nats (Default)
|
|
* cc-metric-store (Default)
|
|
* influxdb (Default)
|
|
* openldap (Default)
|
|
* mysql (Optional)
|
|
* mariadb (Optional)
|
|
* phpmyadmin (Optional)
|
|
|
|
The setup comes with fixture data for a Job archive, cc-metric-store checkpoints, InfluxDB, MySQL, and a LDAP user directory.
|
|
|
|
## Known Issues
|
|
|
|
* `docker-compose` installed on Ubuntu (18.04, 20.04) via `apt-get` can not correctly parse `docker-compose.yml` due to version differences. Install latest version of `docker-compose` from https://docs.docker.com/compose/install/ instead.
|
|
* You need to ensure that no other web server is running on ports 8080 (cc-backend), 8081 (phpmyadmin), 8084 (cc-metric-store), 8086 (nfluxDB), 4222 and 8222 (Nats), or 3306 (MySQL). If one or more ports are already in use, you habe to adapt the related config accordingly.
|
|
* Existing VPN connections sometimes cause problems with docker. If `docker-compose` does not start up correctly, try disabling any active VPN connection. Refer to https://stackoverflow.com/questions/45692255/how-make-openvpn-work-with-docker for further information.

|
## Configuration Templates
|
|
|
|
Located in `./templates`
|
|
* `docker-compose.yml.default`: Docker-Compose file to setup cc-metric-store, InfluxDB, MariaDB, PhpMyadmin, and LDAP containers (Default). Used in `setupDev.sh`.
|
|
* `docker-compose.yml.mysql`: Docker-Compose configuration template if MySQL is desired instead of MariaDB.
|
|
* `env.default`: Environment variables for setup with cc-metric-store, InfluxDB, MariaDB, PhpMyadmin, and LDAP containers (Default). Used in `setupDev.sh`.
|
|
* `env.mysql`: Additional environment variables required if MySQL is desired instead of MariaDB.
|
|
|
|
## Setup
|
|
|
|
1. Clone `cc-backend` repository in chosen base folder: `$> git clone https://github.com/ClusterCockpit/cc-backend.git`
|
|
|
|
2. Run `$ ./setupDev.sh`: **NOTICE** The script will download files of a total size of 338MB (mostly for the InfluxDB data).
|
|
|
|
3. The setup-script launches the supporting container stack in the background automatically if everything went well. Run `$> ./cc-backend/cc-backend` to start `cc-backend.`
|
|
|
|
4. By default, you can access `cc-backend` in your browser at `http://localhost:8080`. You can shut down the cc-backend server by pressing `CTRL-C`, remember to also shut down all containers via `$> docker-compose down` afterwards.
|
|
|
|
5. You can restart the containers with: `$> docker-compose up -d`.
|
|
|
|
## Post-Setup Adjustment for using `influxdb`
|
|
|
|
When using `influxdb` as a metric database, one must adjust the following files:
|
|
* `cc-backend/var/job-archive/emmy/cluster.json`
|
|
* `cc-backend/var/job-archive/woody/cluster.json`
|
|
|
|
In the JSON, exchange the content of the `metricDataRepository`-Entry (By default configured for `cc-metric-store`) with:
|
|
```
|
|
"metricDataRepository": {
|
|
"kind": "influxdb",
|
|
"url": "http://localhost:8086",
|
|
"token": "egLfcf7fx0FESqFYU3RpAAbj",
|
|
"bucket": "ClusterCockpit",
|
|
"org": "ClusterCockpit",
|
|
"skiptls": false
|
|
}
|
|
```
|
|
|
|
|
|
## Usage
|
|
|
|
Credentials for the preconfigured demo user are:
|
|
* User: `demo`
|
|
* Password: `AdminDev`
|
|
|
|
You can also login as regular user using any credential in the LDAP user directory at `./data/ldap/users.ldif`.

TODO: Update job archive and all other metric data.
|
|
The job archive with 1867 jobs originates from the second half of 2020.
|
|
Roughly 2700 jobs from the first week of 2021 are loaded with data from InfluxDB.
|
|
Some views of ClusterCockpit (e.g. the Users view) show the last week or month.
|
|
To show some data there you have to set the filter to time periods with jobs (August 2020 to January 2021).
