# remote targets
|
|
|
|
`kustomize build` can be run on a URL.
|
|
|
|
The effect is the same as cloning the repo, checking out a particular
|
|
_ref_ (commit hash, branch name, release tag, etc.),
|
|
then running `kustomize build` against the desired
|
|
directory in the local copy.
|
|
|
|
To try this immediately, run a build against the kustomization
|
|
in the [multibases](multibases/README.md) example. There's
|
|
one pod in the output:
|
|
|
|
<!-- @remoteOverlayBuild @testAgainstLatestRelease -->
|
|
|
|
```
|
|
target="github.com/kubernetes-sigs/kustomize/examples/multibases/dev/?ref=v1.0.6"
|
|
test 1 == \
|
|
$(kustomize build $target | grep dev-myapp-pod | wc -l); \
|
|
echo $?
|
|
```
|
|
|
|
Run against the overlay in that example to get three pods
|
|
(the overlay combines the dev, staging and prod bases for
|
|
someone who wants to send them all at the same time):
|
|
|
|
<!-- @remoteBuild @testAgainstLatestRelease -->
|
|
```
|
|
target="https://github.com/kubernetes-sigs/kustomize/examples/multibases?ref=v1.0.6"
|
|
test 3 == \
|
|
$(kustomize build $target | grep cluster-a-.*-myapp-pod | wc -l); \
|
|
echo $?
|
|
```
|
|
|
|
A base can be a URL:
|
|
|
|
<!-- @createOverlay @testAgainstLatestRelease -->
|
|
```
|
|
DEMO_HOME=$(mktemp -d)
|
|
|
|
cat <<EOF >$DEMO_HOME/kustomization.yaml
|
|
resources:
|
|
- github.com/kubernetes-sigs/kustomize/examples/multibases?ref=v1.0.6
|
|
namePrefix: remote-
|
|
EOF
|
|
```
|
|
|
|
Build this to confirm that all three pods from the base
|
|
have the `remote-` prefix.
|
|
|
|
<!-- @remoteBases @testAgainstLatestRelease -->
|
|
```
|
|
test 3 == \
|
|
$(kustomize build $DEMO_HOME | grep remote-.*-myapp-pod | wc -l); \
|
|
echo $?
|
|
```
|
|
|
|
## URL format
|
|
|
|
The url should follow
|
|
[hashicorp/go-getter URL format](https://github.com/hashicorp/go-getter#url-format).
|
|
Here are some example urls pointing to Github repos following this convention.
|
|
|
|
- a repo with a root level kustomization.yaml
|
|
|
|
`github.com/Liujingfang1/mysql`
|
|
- a repo with a root level kustomization.yaml on branch test
|
|
|
|
`github.com/Liujingfang1/mysql?ref=test`
|
|
- a subdirectory in a repo on version v1.0.6
|
|
|
|
`github.com/kubernetes-sigs/kustomize/examples/multibases?ref=v1.0.6`
|
|
- a subdirectory in a repo on branch repoUrl2
|
|
|
|
`github.com/Liujingfang1/kustomize/examples/helloWorld?ref=repoUrl2`
|
|
- a subdirectory in a repo on commit `7050a45134e9848fca214ad7e7007e96e5042c03`
|
|
|
|
`github.com/Liujingfang1/kustomize/examples/helloWorld?ref=7050a45134e9848fca214ad7e7007e96e5042c03`
