Custom invocation image does not work if removing # PORTER_INIT
Closed this issue · 0 comments

Describe the bug
https://getporter.org/docs/bundle/custom-dockerfile/#porter_init indicates that # PORTER_INIT could be removed:
When that line is omitted, the lines are inserted after the FROM statement at the top of your template.
In the porter create template, it is placed after the FROM, so it should not make a difference if the line is there or not.
To Reproduce
Run the following:
mkdir custom-invocation-bundle
cd custom-invocation-bundle
porter create
echo "Removing # PORTER_INIT"
sed -i 's/# PORTER_INIT//g' template.Dockerfile
echo "Adjusting to use template.Dockerfile explicitly"
sed -i 's/#dockerfile: template.Dockerfile/dockerfile: template.Dockerfile/g' porter.yaml
porter build
Expected behavior
The build should succeed.
