jsonnet-bundler-ng
The jsonnet-bundler-ng is a fork of jsonnet-bundler,
a package manager for jsonnet.
Install
go install -a github.com/dadav/jsonnet-bundler-ng/cmd/jb-ng@latest
Package Install
Features
- Fetches transitive dependencies
- Can vendor subtrees, as opposed to whole repositories
Current Limitations
- Always downloads entire dependent repositories, even when updating
- If two dependencies depend on the same package (diamond problem), they must require the same version
Example Usage
Initialize your project:
mkdir myproject
cd myproject
jb-ng init
The existence of the jsonnetfile.json
file means your directory is now a
jsonnet-bundler package that can define dependencies.
To depend on another package (another Github repository):
Note that your dependency need not be initialized with a jsonnetfile.json
.
If it is not, it is assumed it has no transitive dependencies.
jb-ng install https://github.com/anguslees/kustomize-libsonnet
Now write myconfig.jsonnet
, which can import a file from that package.
Remember to use -J vendor
when running Jsonnet to include the vendor tree.
local kustomize = import 'kustomize-libsonnet/kustomize.libsonnet';
local my_resource = {
metadata: {
name: 'my-resource',
},
};
kustomize.namePrefix('staging-')(my_resource)
To depend on a package that is in a subtree of a Github repo (this package also
happens to bring in a transitive dependency):
jb-ng install https://github.com/prometheus-operator/prometheus-operator/jsonnet/prometheus-operator
Note that if you are copy pasting from the Github website's address bar,
remove the tree/master
from the path.
If pushed to Github, your project can now be referenced from other packages in
the same way, with its dependencies fetched automatically.
