I have no ideas what I am doing wrong. Just running this simple bash script on my pipeline. It also does not work when I test it locally. Same error.
refresh.sh
#!/bin/sh
# refresh.sh
# Create a kustomization.yaml and then add all kubernetes YAMLs into resources...
echo -n "
# built by ./refresh.sh
apiVersion: kustomize.config.k8s.io/v1beta1
kind: Kustomization
resources:
" > kustomization.yaml
yamls=$(find . -type f -name "*.yaml" | grep -v kustomization.yaml)
for y in ${yamls[@]}; do
kustomize edit add resource $y
done
Error:
./refresh.sh: line 16: syntax error: bad substitution
my .gitlab-ci.yml
image:
name: openpolicyagent/conftest:latest
stages:
- kustomize
- policy
kustomize:
stage: kustomize
script:
- echo "Running test 1..."
- chmod +x refresh.sh
- ./refresh.sh
policy:
stage: policy
script:
- echo "Running test 2"
- kubectl kustomize | conftest test -
- rm kustomization.yaml
Also I can see my script listed on my current directory on the logs when I add ls -al in the pipeline kustomize stage so not sure what the issue is:
$ ls -al

Your first error (file not found) was probably caused by bash not being available in the openpolicyagent/conftest:latest container. When you changed the interpreter to /bin/sh the error now happens because of this line:
for y in ${yamls[@]}; do
POSIX sh doesn't support array references. And $yamls is not an array anyway, so you probably should use just $yamls instead of ${yamls[@]}.
