Describe the bug
When using the hashicorp/terraform official terraform container, checkly plugin fails to run.
While I don't expect you to make a special plugin binary to cover this use case, you may want to add a note to the documentation. It's a common issue with golang programs running in alpine linux and can be hard to troubleshoot because the error message (no such file or directory) doesn't really point you in the right direction.
Version
What version of the Checkly Terraform provider are you using? e.g. v0.6.1
v0.6.6
To Reproduce
Steps to reproduce the behavior:
Use the checkly.tf resource file included below. Also uses install_checkly_plugin.sh included below which is a workaround to issue #35

Terraform has been successfully initialized!
You may now begin working with Terraform. Try running "terraform plan" to see
any changes that are required for your infrastructure. All Terraform commands
should now work.
If you ever set or change modules or backend configuration for Terraform,
rerun this command to reinitialize your working directory. If you forget, other
commands will detect it and remind you to do so if necessary.
/run # terraform apply
var.checkly_api_key
Enter a value: XXXXXXX
Error: Could not load plugin
Plugin reinitialization required. Please run "terraform init".
Plugins are external binaries that Terraform uses to access and manipulate
resources. The configuration provided requires plugins which can't be located,
don't satisfy the version constraints, or are otherwise incompatible.
Terraform automatically discovers provider requirements from your
configuration, including providers used in child modules. To see the
requirements and constraints, run "terraform providers".
Failed to instantiate provider "local/checkly/checkly" to obtain schema:
fork/exec
.terraform/plugins/local/checkly/checkly/0.6.6/linux_amd64/terraform-provider-checkly_v0.6.6:
no such file or directory
Root cause
The root cause is that the checkly plugin was built with glibc, and the hashicorp/terraform container is based on alpine, which uses musl I think which isn't compatible with glibc dynamically linked binaries.

Workaround
Two options come to mind, although there are probably several others.
-
Build your own terraform container based on golang:buster. You could base it on the Dockerfile at https://github.com/hashicorp/terraform/blob/master/Dockerfile
-
Add the package libc6-compat to the hashicorp/terraform container before attempting to run terraform apply:
/run # apk add libc6-compat
(1/2) Upgrading musl (1.1.24-r8 -> 1.1.24-r9)
(2/2) Installing libc6-compat (1.1.24-r9)
OK: 38 MiB in 38 packages
/run # /root/.terraform.d/plugins/local/checkly/checkly/0.6.6/linux_amd64/terraform-provider-checkly_v0.6.6
This binary is a plugin. These are not meant to be executed directly.
Please execute the program that consumes these plugins, which will
load any plugins automatically
^ Now the checkly plugin binary will execute instead of saying no such file or directory.
terraform apply also works now:
/run # terraform apply
var.checkly_api_key
Enter a value: XXXX
An execution plan has been generated and is shown below.
Resource actions are indicated with the following symbols:

Terraform will perform the following actions:
# checkly_check.example-check will be created
+ resource "checkly_check" "example-check" {
+ activated = true
+ degraded_response_time = 15000

}
Plan: 1 to add, 0 to change, 0 to destroy.
