#### Updating Kubernetes
|
|
|
|
To update Kubernetes, follow these steps:
|
|
|
|
1. Make a clean GOPATH, with minikube in it.
|
|
This isn't strictly necessary, but it usually helps.
|
|
|
|
```shell
|
|
mkdir -p $HOME/newgopath/src/k8s.io
|
|
export GOPATH=$HOME/newgopath
|
|
cd $HOME/newgopath/src/k8s.io
|
|
git clone https://github.com/kubernetes/minikube.git
|
|
```
|
|
|
|
2. Copy your vendor directory back out to the new GOPATH.
|
|
|
|
```shell
|
|
cd minikube
|
|
godep restore ./...
|
|
```
|
|
|
|
3. Kubernetes should now be on your GOPATH. Check it out to the right version.
|
|
Make sure to also fetch tags, as Godep relies on these.
|
|
|
|
```shell
|
|
cd $GOPATH/src/k8s.io/kubernetes
|
|
git fetch --tags
|
|
```
|
|
|
|
Then list all available Kubernetes tags:
|
|
|
|
```shell
|
|
git tag
|
|
...
|
|
v1.2.4
|
|
v1.2.4-beta.0
|
|
v1.3.0-alpha.3
|
|
v1.3.0-alpha.4
|
|
v1.3.0-alpha.5
|
|
...
|
|
```
|
|
|
|
Then checkout the correct one and update its dependencies with:
|
|
|
|
```shell
|
|
git checkout $DESIREDTAG
|
|
godep restore ./...
|
|
```
|
|
|
|
4. Build and test minikube, making any manual changes necessary to build.
|
|
|
|
5. Update godeps
|
|
|
|
```shell
|
|
cd $GOPATH/src/k8s.io/minikube
|
|
rm -rf Godeps/ vendor/
|
|
godep save ./...
|
|
```
|
|
|
|
6. Verify that the correct tag is marked in the Godeps.json file by running this script:
|
|
|
|
```shell
|
|
python hack/get_k8s_version.py
|
|
-X k8s.io/minikube/vendor/k8s.io/kubernetes/pkg/version.gitCommit=caf9a4d87700ba034a7b39cced19bd5628ca6aa3 -X k8s.io/minikube/vendor/k8s.io/kubernetes/pkg/version.gitVersion=v1.3.0-beta.2 -X k8s.io/minikube/vendor/k8s.io/kubernetes/pkg/version.gitTreeState=clean
|
|
```
|
|
|
|
The `-X k8s.io/minikube/vendor/k8s.io/kubernetes/pkg/version.gitVersion` flag should contain the right tag.
|
|
|
|
Once you've build and started minikube, you can also run:
|
|
|
|
```shell
|
|
kubectl version
|
|
Client Version: version.Info{Major:"1", Minor:"2", GitVersion:"v1.2.4", GitCommit:"3eed1e3be6848b877ff80a93da3785d9034d0a4f", GitTreeState:"clean"}
|
|
Server Version: version.Info{Major:"1", Minor:"3+", GitVersion:"v1.3.0-beta.2", GitCommit:"caf9a4d87700ba034a7b39cced19bd5628ca6aa3", GitTreeState:"clean"}
|
|
```
|
|
|
|
The Server Version should contain the right tag in `version.Info.GitVersion`.
|
|
|
|
If any manual changes were required, please commit the vendor changes separately.
|
|
This makes the change easier to view in Github.
|
|
|
|
```shell
|
|
git add vendor/
|
|
git commit -m "Updating Kubernetes to foo"
|
|
git add --all
|
|
git commit -m "Manual changes to update Kubernetes to foo"
|
|
```
|
|
|
|
As a final part of updating kubernetes, a new version of localkube should be uploaded to GCS so that users can select this version of kubernetes/localkube in later minikube/localkube builds. For instructions on how to do this, see [LOCALKUBE_RELEASING.md](https://github.com/kubernetes/minikube/blob/master/LOCALKUBE_RELEASING.md)
