# Configuration
|
|
|
|
By default, all vieter commands try to read in the TOML file `~/.vieterrc` for
|
|
configuration. The location of this file can be changed by using the `-f` flag.
|
|
|
|
If the above file doesn't exist or you wish to override some of its settings,
|
|
configuration is also possible using environment variables. Every variable in
|
|
the config file has a respective environment variable of the following form:
|
|
say the variable is called `api_key`, then the respective environment variable
|
|
would be `VIETER_API_KEY`. In essence, it's the variable in uppercase prepended
|
|
with `VIETER_`.
|
|
|
|
If a variable is both present in the config file & as an environment variable,
|
|
the value in the environment variable is used.
|
|
|
|
{{< hint info >}}
|
|
**Note**
|
|
All environment variables can also be provided from a file by appending them
|
|
with `_FILE`. This for example allows you to provide the API key from a Docker
|
|
secrets file.
|
|
{{< /hint >}}
|
|
|
|
## Commands
|
|
|
|
The first argument passed to Vieter determines which command you wish to use.
|
|
Each of these can contain subcommands (e.g. `vieter targets list`), but all
|
|
subcommands will use the same configuration. Below you can find the
|
|
configuration variable required for each command.
|
|
|
|
### `vieter server`
|
|
|
|
* `port`: HTTP port to run on
|
|
* Default: `8000`
|
|
* `log_level`: log verbosity level. Value should be one of `FATAL`, `ERROR`,
|
|
`WARN`, `INFO` or `DEBUG`.
|
|
* Default: `WARN`
|
|
* `pkg_dir`: where Vieter should store the actual package archives.
|
|
* `data_dir`: where Vieter stores the repositories, log file & database.
|
|
* `api_key`: the API key to use when authenticating requests.
|
|
* `default_arch`: this setting serves two main purposes:
|
|
* Packages with architecture `any` are always added to this architecture.
|
|
This prevents the server from being confused when an `any` package is
|
|
published as the very first package for a repository.
|
|
* Targets added without an `arch` value use this value instead.
|
|
* `global_schedule`: build schedule for any target that does not have a
|
|
schedule defined. For information about this syntax, see
|
|
[here](/usage/builds/schedule).
|
|
* Default: `0 3` (3AM every night)
|
|
* `base_image`: Docker image to use when building a package. Any Pacman-based
|
|
distro image should work, as long as `/etc/pacman.conf` is used &
|
|
`base-devel` exists in the repositories. Make sure that the image supports
|
|
the architecture of your cron daemon.
|
|
* Default: `archlinux:base-devel` (only works on `x86_64`). If you require
|
|
`aarch64` support, consider using
|
|
[`menci/archlinuxarm:base-devel`](https://hub.docker.com/r/menci/archlinuxarm)
|
|
([GitHub](https://github.com/Menci/docker-archlinuxarm)). This is the
|
|
image used for the Vieter CI builds.
|
|
* `max_log_age`: maximum age of logs (in days). Logs older than this will get
|
|
cleaned by the log removal daemon. If set to zero, no logs are ever removed.
|
|
The age of logs is determined by the time the build was started.
|
|
* Default: `0`
|
|
* `log_removal_schedule`: cron schedule defining when to clean old logs.
|
|
* Default: `0 0` (every day at midnight)
|
|
|
|
### `vieter cron`
|
|
|
|
* `log_level`: log verbosity level. Value should be one of `FATAL`, `ERROR`,
|
|
`WARN`, `INFO` or `DEBUG`.
|
|
* Default: `WARN`
|
|
* `log_file`: log file to write logs to.
|
|
* Default: `vieter.log` (in `data_dir`)
|
|
* `address`: *public* URL of the Vieter repository server to build for. From
|
|
this server the list of Git repositories is retrieved. All built packages are
|
|
published to this server.
|
|
* `api_key`: API key of the above server.
|
|
* `data_dir`: directory to store log file in.
|
|
* `base_image`: Docker image to use when building a package. Any Pacman-based
|
|
distro image should work, as long as `/etc/pacman.conf` is used &
|
|
`base-devel` exists in the repositories. Make sure that the image supports
|
|
the architecture of your cron daemon.
|
|
* Default: `archlinux:base-devel` (only works on `x86_64`). If you require
|
|
`aarch64` support, consider using
|
|
[`menci/archlinuxarm:base-devel`](https://hub.docker.com/r/menci/archlinuxarm)
|
|
([GitHub](https://github.com/Menci/docker-archlinuxarm)). This is the image
|
|
used for the Vieter CI builds.
|
|
* `max_concurrent_builds`: how many builds to run at the same time.
|
|
* Default: `1`
|
|
* `api_update_frequency`: how frequently (in minutes) to poll the Vieter
|
|
repository server for a new list of Git repositories to build.
|
|
* Default: `15`
|
|
* `image_rebuild_frequency`: Vieter periodically builds a builder image using
|
|
the configured base image. This makes sure build containers do not have to
|
|
download a lot of packages when updating their system. This setting defines
|
|
how frequently (in minutes) to rebuild this builder image.
|
|
* Default: `1440` (every 24 hours)
|
|
* `global_schedule`: build schedule for any Git repository that does not have a
|
|
schedule defined. For information about this syntax, see
|
|
[here](/usage/builds/schedule).
|
|
* Default: `0 3` (3AM every night)
|
|
|
|
### `vieter logs`
|
|
|
|
* `api_key`: the API key to use when authenticating requests.
|
|
* `address`: Base URL of your Vieter instance, e.g. https://example.com
|
|
|
|
### `vieter targets`
|
|
|
|
* `api_key`: the API key to use when authenticating requests.
|
|
* `address`: Base URL of your Vieter instance, e.g. https://example.com
|
|
* `base_image`: image to use when building a package using `vieter targets
|
|
build`.
|
|
* Default: `archlinux:base-devel`
|
|
|
|
### `vieter agent`
|
|
|
|
* `log_level`: log verbosity level. Value should be one of `FATAL`, `ERROR`,
|
|
`WARN`, `INFO` or `DEBUG`.
|
|
* Default: `WARN`
|
|
* `address`: *public* URL of the Vieter repository server to build for. From
|
|
this server jobs are retrieved. All built packages are published to this
|
|
server.
|
|
* `api_key`: API key of the above server.
|
|
* `data_dir`: directory to store log file in.
|
|
* `max_concurrent_builds`: how many builds to run at the same time.
|
|
* Default: `1`
|
|
* `polling_frequency`: how often (in seconds) to poll the server for new
|
|
builds. Note that the agent might poll more frequently when it's actively
|
|
processing builds.
|
|
* `image_rebuild_frequency`: Vieter periodically builds images that are then
|
|
used as a basis for running build containers. This is to prevent each build
|
|
from downloading an entire repository worth of dependencies. This setting
|
|
defines how frequently (in minutes) to rebuild these images.
|
|
* Default: `1440` (every 24 hours)
|
|
* `arch`: architecture for which this agent should pull down builds (e.g.
|
|
`x86_64`)
