First of all Packer doesn't work with remote Docker hosts. (I updated the docs to be more clear on this just some days ago, pending deploy, see https://github.com/hashicorp/packer/pull/5992)
If you instead run a Jenkins agent on the host you would like to run the packer build on everything should work out-of-the-box. If not the best way to troubleshot it is to add a sleep into the container and jump in to it and verify that you get appropriate AWS access keys and roles from the metadata api: curl http://169.254.169.254/latest/meta-data/iam/security-credentials/ <role-name> On 14 March 2018 at 10:10, Alvaro Miranda Aguilera <[email protected]> wrote: > Hello > > If I understand correctly, you want to run packer inside the EC2 that have > jenkins to build docker inside the EC2 with docker, right? > > Can you setup DOCKER_HOST variable before running packer and testing you > can list/build using docker commands ? > > If this is setup, share your template.json output of docker version on the > remote EC2 machine and packer build debug logs > > Thanks > Alvaro > > On Wed, Mar 14, 2018 at 4:35 AM, Ramanathan Muthaiah <[email protected] > > wrote: > >> Hello, >> >> In a AWS cloud environment (personal account), I have a EC2 instance >> acting as Docker Host and another EC2 instance that runs Jenkins.
