# CentOS Stream Compose Process

This document describes the process of how to run a CentOS Stream compose and sync it to stage.

CentOS Stream composes happen on **composer01.rdu2.centos.org** as the **compose** user.
They are created using the [pungi](https://pagure.io/pungi) tool with configurations located in */compose/pungi-centos-stream/*.
They are stored under the */compose/trees/* directory.
Pushing a compose requires syncing it to the staging location */old-compose/staged/8-stream/* with a staging script.
Later they are synced from staging to QA.

## Main Distro

### Compose

```
sudo -u compose pungi-koji \
    --config /compose/pungi-centos-stream/c8-stream.conf \
    --old-composes /compose/trees \
    --target /compose/trees \
    --supported \
    --nightly
```

### Stage

```
sudo -u compose /compose/centos8-buildsys-tools-private/stage-stream.sh
```

### Treeinfo

As pungi only generates the treeinfo for BaseOS, we need to add the *treeinfo* of AppStream to the BaseOS treeinfo.

```
/compose/centos8-buildsys-tools-private/fix_treeinfos /old-compose/staged/8-stream/
```

## Cloud Images

### Compose

```
sudo -u compose pungi-koji \
    --config /compose/pungi-centos-stream/c8-stream-cloud.conf \
    --old-composes /compose/trees \
    --target /compose/trees \
    --label Update-1.0
```

### Stage

    --skip-phase buildinstall \
    --skip-phase createiso \
