I keep getting this error:

docker run --interactive --tty --rm \
  --env-file .packerenv \
  --env-file .goenv \
  --volume "${ISOFILEPATH}:/edge/vmware/packer/build" \
  ghcr.io/spectrocloud/tutorials:1.0.8 \
  sh -c "source /edge/vmware/clone_vm_template/setenv.sh && govc datastore.rm -ds=$vcenter_datastore /packer_cache && cd /edge/vmware/packer/ && packer build -force --var-file=vsphere.hcl build.pkr.hcl"
govc: default datastore resolves to multiple instances, please specify

If I go inside the docker container and run source /edge/vmware/clone_vm_template/setenv.sh && govc datastore.rm -ds=$vcenter_datastore /packer_cache && cd /edge/vmware/packer/ && packer build -force --var-file=vsphere.hcl build.pkr.hcl I do not get the same error and everything is fine.

Don't quite understand why this is happening. I tried googling this error and wasn't really able to find much about it that seems to apply to us. Do you have any ideas? @karl-cardenas-coding

[karl-cardenas-coding]

Hmm....🤔 I wonder if the $ used in the -ds flag is resolving incorrectly

[lennessyy]

That does seem to be the case. I tried to have it echo the variable and it did not give me a response. I'll look into it more this week

[karl-cardenas-coding]

Try wrapping the sh command in single to ticks, and use double quotes to escape the env variable.

sh -c 'source /edge/vmware/clone_vm_template/setenv.sh && echo "$vcenter_datastore"> /edge/vmware/packer/build/echo.txt'

[karl-cardenas-coding]

Changes look good @lennessyy just some minor suggestions . Let's make sure the tutorial image is released and available before we merge the PR.
