Having some trouble getting the docker provider (kreuzwerker/docker) running on terraform cloud. I’ve tried several different ‘host’ addresses for the provider when initializing (I’m using CDKTF), but always get the same error (obviously with different paths): Error: Error pinging Docker server: Ca…

Im having the same issue. If anyone can point us into a direction that fixes this that would be great!

i think terraform cloud agent seems not have docker engine installed by default there so it won’t work

Hi @jaismith , The default remote operations mechanism where Terraform is running in an execution environment managed by Terraform Cloud itself is not appropriate for working with APIs that are accessible only on your local network or local computer.

You need to change the execution mode in the Cloud settings to local as described here: [image] Import Terraform configuration | Terraform | HashiCorp Developer Use configuration to import existing infrastructure into Terraform. Review important considerations when bringing infrastructu…

I had the same problem but finally managed to fix. Before running terraform apply, check where the docker daemon is running using docker context ls. The default option may not work, thus the error most people get. Pick the one with *. Then go to the file <main.tf>, edit it to reflect the host as bel…
