Building, Testing, and Contributing
If you have
make and docker, you can build for your environment with just
make. Since the Makefile uses docker to build, it's not generally essential to install go on your machine, although it will make things easier.
Build/test/check static analysis with:
The binaries are built into .gotmp/bin; although normal command-line
go build or
go install will work (and everything works fine with IDEs like Goland or vscode) the official build technique is via
make which uses a completely consistent golang-build-container so that the build is identical no matter what machine or OS it might be built on.
Normal test invocation is just
make test. Run a single test with an invocation like
go test -v -run TestDevAddSites ./pkg/... or
make testpkg TESTARGS="-run TestDevAddSites".
To see which ddev commands the tests are executing, set the environment variable DDEV_DEBUG=true.
Use GOTEST_SHORT=true to run just one CMS in each test.
Docker container development
The docker containers that ddev uses are included in the containers/ directory:
- containers/ddev-webserver: Provides the web servers (the "web" container).
- containers/ddev-dbserver: Provides the "db" container.
- containers/phpmyadmin: Provides the phpmyadmin (dba) container
- containers/ddev-router: The router image
When changes are made to a container, they have to be temporarily pushed to a tag that is preferably the same as the branch name of the PR, and the tag updated in pkg/version/version.go. Just ask if you need a container pushed to support a PR.
