+# Builds In-depth
+
+For those interested, this page describes how the build system works
+internally.
+
+## Builder image
+
+Every cron daemon perodically creates a builder image that is then used as a
+base for all builds. This is done to prevent build containers having to pull
+down a bunch of updates when they update their system.
+
+The build container is created by running the following commands inside a
+container started from the image defined in `base_image`:
+
+```sh
+# Update repos & install required packages
+pacman -Syu --needed --noconfirm base-devel git
+# Add a non-root user to run makepkg
+groupadd -g 1000 builder
+useradd -mg builder builder
+# Make sure they can use sudo without a password
+echo 'builder ALL=(ALL) NOPASSWD: ALL' >> /etc/sudoers
+# Create the directory for the builds & make it writeable for the
+# build user
+mkdir /build
+chown -R builder:builder /build
+```
+
+This script updates the packages to their latest versions & creates a non-root
+user to use when running `makepkg`.
+
+This script is base64-encoded & passed to the container as an environment
+variable. The container's entrypoint is set to `/bin/sh -c` & its command
+argument to `echo $BUILD_SCRIPT | base64 -d | /bin/sh -e`, with the
+`BUILD_SCRIPT` environment variable containing the base64-encoded script.
+
+Once the container exits, a new Docker image is created from it. This image is
+then used as the base for any builds.
+
+## Running builds
+
+Each build has its own Docker container, using the builder image as its base.
+The same base64-based technique as above is used, just with a different script.
+To make the build logs more clear, each command is appended by an echo command
+printing the next command to stdout.
+
+Given the Git repository URL is `https://examplerepo.com` with branch `main`,
+the URL of the Vieter server is `https://example.com` and `vieter` is the
+repository we wish to publish to, we get the following script:
+
+```sh
+echo -e '+ echo -e '\''[vieter]\\nServer = https://example.com/$repo/$arch\\nSigLevel = Optional'\'' >> /etc/pacman.conf'
+echo -e '[vieter]\nServer = https://example.com/$repo/$arch\nSigLevel = Optional' >> /etc/pacman.conf
+echo -e '+ pacman -Syu --needed --noconfirm'

+echo -e '+ MAKEFLAGS="-j$(nproc)" makepkg -s --noconfirm --needed && for pkg in $(ls -1 *.pkg*); do curl -XPOST -T "$pkg" -H "X-API-KEY: $API_KEY" https://example.com/vieter/publish; done'

+```
+
+This script:
+
+1. Adds the target repository as a repository in the build container
+2. Updates mirrors & packages
+3. Clones the Git repository
+4. Runs `makepkg` without building to calculate `pkgver`
+5. Checks whether the package version is already present on the server
+6. If not, run `makepkg` & publish any generated package archives to the server

-# Cleanup

-Vieter stores the logs of every single package build. While this is great for
-debugging why builds fail, it also causes an active or long-running Vieter
-instance to accumulate thousands of logs.
-
-To combat this, a log removal daemon can be enabled that periodically removes
-old build logs. By starting your server with the `max_log_age` variable (see
-[Configuration](/configuration#vieter-server)), a daemon will get enabled that
-periodically removes logs older than this setting. By default, this will happen
-every day at midnight, but this behavior can be changed using the
-`log_removal_schedule` variable.
-
-{{< hint info >}}
-**Note**  
-The daemon will always run a removal of logs on startup. Therefore, it's
-possible the daemon will be *very* active when first enabling this setting.
-After the initial surge of logs to remove, it'll calm down again.

+* Overwrite values in config file using environment variables
+* Allow default values in config struct
