## Build k3s from source
|
|
|
|
Before getting started, bear in mind that this repository includes all of Kubernetes history, so consider shallow cloning with (`--depth 1`) to speed up the process.
|
|
|
|
```bash
|
|
git clone --depth 1 https://github.com/k3s-io/k3s.git
|
|
```
|
|
|
|
The k3s build process requires some autogenerated code and remote artifacts that are not checked in to version control. To prepare these resources for your build environment, run:
|
|
|
|
```bash
|
|
mkdir -p build/data && make download && make generate
|
|
```
|
|
|
|
To build the full release binary, you may now run `make`, which will create `./dist/artifacts/k3s`.
|
|
|
|
To build the binaries using `make` without running linting (i.e.: if you have uncommitted changes):
|
|
|
|
```bash
|
|
SKIP_VALIDATE=true make
|
|
```
|
|
|
|
In case you make any changes to [go.mod](go.mod), you should run `go mod tidy` before running `make`.
|
|
|
|
### macOS considerations
|
|
|
|
The shell scripts in charge of the build process (the ones behind `make`) rely on GNU utils (i.e., `sed`), [which slightly differ on macOS](https://unix.stackexchange.com/a/79357). So, if you need to build k3s on a macOS environment, it is suggested to use the virtual machine defined on this repository's [Vagrantfile](Vagrantfile) to perform the tasks mentioned above.
|
|
|
|
To start the virtual machine, you will need [vagrant](https://www.vagrantup.com/) and [virtual box](https://www.virtualbox.org/) installed. Then prompt:
|
|
|
|
```bash
|
|
$ vagrant up
|
|
[... vm provisioning logs ...]
|
|
```
|
|
|
|
Once the virtual machine is provisioned, you should be able to ssh into it by doing `vagrant ssh` and perform any building task there:
|
|
|
|
```bash
|
|
$ vagrant ssh
|
|
[... ssh connection logs ..]
|
|
$ uname -a
|
|
Linux k3s-0-alpine312 5.11.0-41-generic
|
|
$ make
|
|
[... k3s build logs ...]
|
|
```
|
|
|
|
All the artifacts built within the VM will be synchronized with the directory where the `vagrant up` command was issued. For vagrant related commands please refer to [its cli documentation](https://www.vagrantup.com/docs/cli).
