This repository provides Go bindings for CRIU. The code is based on the Go-based PHaul implementation from the CRIU repository. For easier inclusion into other Go projects, the CRIU Go bindings have been moved to this repository.
The Go bindings provide an easy way to use the CRIU RPC calls from Go without the need to set up all the infrastructure to make the actual RPC connection to CRIU.
The following example would print the version of CRIU:
import (
"log"
"github.com/checkpoint-restore/go-criu/v8"
)
func main() {
c := criu.MakeCriu()
version, err := c.GetCriuVersion()
if err != nil {
log.Fatalln(err)
}
log.Println(version)
}or to just check if at least a certain CRIU version is installed:
c := criu.MakeCriu()
result, err := c.IsCriuAtLeast(31100)The crit package provides bindings to decode, encode, and manipulate
CRIU image files natively within Go. It also provides a CLI tool similar
to the original CRIT Python tool. To get started with this, see the docs
at CRIT (Go library).
The first go-criu release was 3.11 based on CRIU 3.11. The initial plan was to follow CRIU so that go-criu would carry the same version number as CRIU.
As go-criu is imported in other projects and as Go modules are expected to follow Semantic Versioning go-criu will also follow Semantic Versioning starting with the 4.0.0 release.
The following table shows the relation between go-criu and criu versions:
| Major version | Latest release | CRIU version |
|---|---|---|
| v8 | 8.2.0 | 4.2 |
| v7 | 7.2.0 | 3.19 |
| v7 | 7.0.0 | 3.18 |
| v6 | 6.3.0 | 3.17 |
| v5 | 5.3.0 | 3.16 |
| v5 | 5.0.0 | 3.15 |
| v4 | 4.1.0 | 3.14 |
