Using the provider

You would use the epcc-terraform-provider just as any other terraform provider. See the ./examples directory for sample resources and data sources.

See the [Core Terraform Workflow] (https://www.terraform.io/guides/core-workflow.html) page for more info on using Terraform.

Useful commands

Command	Description
go install	Compile the provider. This will build the provider and put the provider binary in the $GOPATH/bin directory.
go generate	Generate or update documentation
make testacc	Runs the full suite of Acceptance tests

Debugging the Provider

1. Run make build

2. Run the following command (assuming you've installed delve)

dlv exec --accept-multiclient --continue --headless ./bin/terraform-provider-epcc --listen=:41837 -- -debug

3. Connect with your Debugger

4. Find the line TF_REATTACH_PROVIDERS in the output

5. When running terraform prefix the above to the command, for example:

TF_REATTACH_PROVIDERS='...' terraform apply

Code Style

Please run gofmt prior to committing, the following pre-commit hook (create and mark executable in .git/hooks/pre-commit) can do this automatically for you

#!/bin/bash

echo "Running commit hook"

echo "Fixing changed files"
git diff --cached --name-only --diff-filter=ACM | grep -E "\.go$" | xargs -n 1 -d "\n" gofmt -s -w

git diff --cached --name-only --diff-filter=ACM | grep -E "\.go$" | xargs git add 

echo "Inspecting all other files"

if [ "$(gofmt -s -l . | wc -l)" -gt 0 ]; then
  echo "Code style differences detected:"
  gofmt -s -l .
  exit 1
fi
