## Example of conversion of a legacy my.jsonnet file
|
||||
|
||||
An example conversion of a legacy custom jsonnet file to release-0.8
|
||||
format can be seen by viewing and comparing this
|
||||
[release-0.3 jsonnet file](./my.release-0.3.jsonnet) (when the github
|
||||
repo was under `https://github.com/coreos/kube-prometheus...`)
|
||||
and the corresponding [release-0.8 jsonnet file](./my.release-0.8.jsonnet).
|
||||
|
||||
These two files have had necessary blank lines added so that they
|
||||
can be compared side-by-side and line-by-line on screen.
|
||||
|
||||
The conversion covers both the change of stopping using ksonnet after
|
||||
release-0.3 and also the major migration after release-0.7 as described in
|
||||
[migration-guide.md](../migration-guide.md)
|
||||
|
||||
The sample files are intended as an example of format conversion and
|
||||
not necessarily best practice for the files in release-0.3 or release-0.8.
|
||||
|
||||
Below are three sample extracts of the conversion as an indication of the
|
||||
changes required.
