# miqt-docker
This is a helper program to quickly run a dockerized MIQT build environment.
This is an optional helper program to quickly run a dockerized MIQT cross-compiler
environment. Many containers are available targeting different OSes and Qt versions.
It also has some built-in commands that can be run either dockerized or natively.
- Supports all available MIQT docker containers
- Use glob matches to automatically pick the highest version container for target
- Automatically build new docker containers or reuse existing, based on content hash of the Dockerfile
- Automatically bind source code volume from current go.mod / go.work / git repository and preserve relative working directory
- Handles bind-mounting the GOCACHE and GOMODCACHE directories
- Handles using the proper uid+gid on Linux
- Automatically detect sudo requirement on Linux

You can specify the environment using a short form of the name. For example,
`win64-static` will be expanded to the regex `/win64.+static/` and pick the
best available match with the highest version number (`win64-cross-go1.24-qt6.8-static`
at time of writing).
This allows you to pin platforms and major versions in build commands while
automatically upgrading to minor versions.
Example build commands:
```bash
miqt-docker macos go build -ldflags '-s -w'
miqt-docker win64-qt6-dynamic go build -ldflags '-s -w -H windowsgui'
miqt-docker native -minify-build
miqt-docker win64-qt6-static -windows-build
miqt-docker win64-qt6-static /bin/bash
miqt-docker android-qt6 -android-build
```
## Comparison to manual Docker commands
You can create a dockerized MIQT build environment yourself using the Dockerfiles
in the `docker/` directory. The benefit of miqt-docker is:
- Embeds all available MIQT docker containers
- Use glob matches to automatically pick the highest version container for target
- Automatically build new docker containers or reuse existing, based on content hash of the Dockerfile
- Consistently named docker images across multiple projects using MIQT
- Automatically bind source code volume from current go.mod / go.work / git repository and preserve relative working directory
- Handles bind-mounting the GOCACHE and GOMODCACHE directories for fast rebuilds
- Handles using the proper uid+gid on Linux
- Automatically detect sudo requirement on Linux
- Convenient predefined tasks
- Advanced build support for Android
