Build from source

Prerequisites

  • Access to a Kubernetes cluster, version 1.7 or later.
  • A DNS server on the cluster
  • kubectl installed
  • Go installed (minimum version 1.8)

Get the source

Option 1) Get latest (recommended)

mkdir $HOME/go
export GOPATH=$HOME/go
go get github.com/vmware-tanzu/velero

Where go is your import path for Go.

For Go development, it is recommended to add the Go import path ($HOME/go in this example) to your path.

Option 2) Release archive

Download the archive named Source code from the release page and extract it in your Go import path as src/github.com/vmware-tanzu/velero.

Note that the Makefile targets assume building from a git repository. When building from an archive, you will be limited to the go build commands described below.

Build

There are a number of different ways to build velero depending on your needs. This section outlines the main possibilities.

When building by using make, it will place the binaries under _output/bin/$GOOS/$GOARCH. For example, you will find the binary for darwin here: _output/bin/darwin/amd64/velero, and the binary for linux here: _output/bin/linux/amd64/velero. make will also splice version and git commit information in so that velero version displays proper output.

Note: velero install will also use the version information to determine which tagged image to deploy. If you would like to overwrite what image gets deployed, use the image flag (see below for instructions on how to build images).

Build the binary

To build the velero binary on your local machine, compiled for your OS and architecture, run one of these two commands:

go build ./cmd/velero
make local

Cross compiling

To build the velero binary targeting linux/amd64 within a build container on your local machine, run:

make build

For any specific platform, run make build-<GOOS>-<GOARCH>.

For example, to build for the Mac, run make build-darwin-amd64.

Velero's Makefile has a convenience target, all-build, that builds the following platforms:

  • linux-amd64
  • linux-arm
  • linux-arm64
  • linux-ppc64le
  • darwin-amd64
  • windows-amd64

Making images and updating Velero

If after installing Velero you would like to change the image used by its deployment to one that contains your code changes, you may do so by updating the image:

kubectl -n velero set image deploy/velero velero=myimagerepo/velero:$VERSION

To build a Velero container image, first set the $REGISTRY environment variable. For example, if you want to build the gcr.io/my-registry/velero-amd64:master image, set $REGISTRY to gcr.io/my-registry. If this variable is not set, the default is velero.

Optionally, set the $VERSION environment variable to change the image tag. Then, run:

make container

For any specific platform, run ARCH=<GOOS>-<GOARCH> make container

For example, to build an image for the Power (ppc64le), run

ARCH=linux-ppc64le make container

Note: By default, ARCH is set to linux-amd64

To push your image to the registry, first set the $REGISTRY environment variable. For example, if you want to push the gcr.io/my-registry/velero-amd64:master image, set $REGISTRY to gcr.io/my-registry. If this variable is not set, the default is velero.

Optionally, set the $VERSION environment variable to change the image tag. Then, run:

make push

For any specific platform, run ARCH=<GOOS>-<GOARCH> make push

For example, to push image for the Power (ppc64le), run

ARCH=linux-ppc64le make push

Note: By default, ARCH is set to linux-amd64

To create your manifest and push to the registry, first set the $REGISTRY environment variable. For example, if you want to create and push the gcr.io/my-registry/velero:master manifest, set $REGISTRY to gcr.io/my-registry. If this variable is not set, the default is velero.

Optionally, set the $VERSION environment variable to change the manifest tag. Then, run:

make manifest

For any specific platform, run MANIFEST_PLATFORMS=<GOARCH> make manifest

For example, to create and push manifest only for amd64, run

MANIFEST_PLATFORMS=amd64 make manifest

Note: By default, MANIFEST_PLATFORMS is set to amd64, ppc64le

To run the entire workflow, run:

REGISTRY=<$REGISTRY> VERSION=<$VERSION> ARCH=<GOOS>-<GOARCH> MANIFEST_PLATFORMS=<GOARCH> make container push manifest

For example, to run the workflow only for amd64

REGISTRY=myrepo VERSION=foo MANIFEST_PLATFORMS=amd64 make container push manifest

Note: By default, ARCH is set to linux-amd64

For example, to run the workflow only for ppc64le

REGISTRY=myrepo VERSION=foo ARCH=linux-ppc64le MANIFEST_PLATFORMS=ppc64le make container push manifest

For example, to run the workflow for all supported platforms

REGISTRY=myrepo VERSION=foo make all-containers all-push all-manifests

Note: By default, MANIFEST_PLATFORMS is set to amd64, ppc64le

Note: if you want to update the image but not change its name, you will have to trigger Kubernetes to pick up the new image. One way of doing so is by deleting the Velero deployment pod:

kubectl -n velero delete pods -l deploy=velero
