Docker
You can use our Docker image to be able to run the TinyGo compiler on your computer without having to install all the dependencies. Read on to learn how.
Installing
docker pull tinygo/tinygo:0.34.0
Using
The paths used here are automatically resolved by tinygo
relative to the installation directory.
For your own code, you will probably want to use absolute paths.
A docker container exists for easy access to the TinyGo CLI. For example, to compile wasm.wasm
for the WebAssembly export example:
docker run --rm -v $(pwd):/src tinygo/tinygo:0.34.0 tinygo build -o wasm.wasm -target=wasm examples/wasm/export
See the WebAssembly page for more information on executing the compiled WebAssembly.
To compile blinky1.hex
targeting an ARM microcontroller, such as the PCA10040:
docker run --rm -v $(pwd):/src tinygo/tinygo:0.34.0 tinygo build -o /src/blinky1.hex -size=short -target=pca10040 examples/blinky1
To compile blinky1.hex
targeting an AVR microcontroller such as the Arduino:
docker run --rm -v $(pwd):/src tinygo/tinygo:0.34.0 tinygo build -o /src/blinky1.hex -size=short -target=arduino examples/blinky1
For projects that have remote dependencies outside of the standard library and
go code within your own project, you will need to map your entire $GOPATH
into the docker image for those dependencies to be found:
docker run -v $GOPATH:/go -e "GOPATH=/go" tinygo/tinygo:0.34.0 tinygo build -o /go/src/github.com/myuser/myrepo/wasm.wasm -target wasm --no-debug /go/src/github.com/myuser/myrepo/wasm-main.go
note: At this time, tinygo does not resolve dependencies from the /vendor/ folder within your project.
For microcontroller development you must flash your hardware devices from your host environment, since you cannot run tinygo flash
from inside the docker container.
So your workflow could be:
- Compile TinyGo code using the Docker container into a HEX file.
- Flash the HEX file from your host environment to the target microcontroller.
Development Builds
You can also use the Docker image with the latest builds from the TinyGo dev
branch where active development takes place:
docker pull tinygo/tinygo-dev:latest
