tfk8s \"Go \"tests\"

\n
\n

\"\"

\n

tfk8s is a tool that makes it easier to work with the Terraform Kubernetes Provider.

\n

If you want to copy examples from the Kubernetes documentation or migrate existing YAML manifests and use them with Terraform without having to convert YAML to HCL by hand, this tool is for you.

\n\n

Demo

\n

\n

Features

\n\n

Install

\n
go install github.com/jrhouston/tfk8s@latest\n
\n

Alternatively, clone this repo and run:

\n
make install\n
\n

If Go's bin directory is not in your PATH you will need to add it:

\n
export PATH=$PATH:$(go env GOPATH)/bin\n
\n

Or you can install via brew for macOS/Linux:

\n
brew install tfk8s\n
\n

On macOS, you can also install via MacPorts:

\n
sudo port install tfk8s\n
\n

Usage

\n
Usage of tfk8s:\n  -f, --file string         Input file containing Kubernetes YAML manifests (default \"-\")\n  -M, --map-only            Output only an HCL map structure\n  -o, --output string       Output file to write Terraform config (default \"-\")\n  -p, --provider provider   Provider alias to populate the provider attribute\n  -s, --strip               Strip out server side fields - use if you are piping from kubectl get\n  -Q, --strip-key-quotes    Strip out quotes from HCL map keys unless they are required.\n  -V, --version             Show tool version\n
\n

Examples

\n

Create Terraform configuration from YAML files

\n
tfk8s -f input.yaml -o output.tf\n
\n

or, using pipes:

\n
cat input.yaml | tfk8s > output.tf\n
\n

input.yaml:

\n
---\napiVersion: v1\nkind: ConfigMap\nmetadata:\n  name: test\ndata:\n  TEST: test
\n

✨✨ magically becomes ✨✨

\n

output.tf:

\n
resource \"kubernetes_manifest\" \"configmap_test\" {\n  manifest = {\n    \"apiVersion\" = \"v1\"\n    \"data\" = {\n      \"TEST\" = \"test\"\n    }\n    \"kind\" = \"ConfigMap\"\n    \"metadata\" = {\n      \"name\" = \"test\"\n    }\n  }\n}
\n

Use with kubectl to output maps instead of YAML

\n
kubectl get ns default -o yaml | tfk8s -M\n
\n
{\n  \"apiVersion\" = \"v1\"\n  \"kind\" = \"Namespace\"\n  \"metadata\" = {\n    \"creationTimestamp\" = \"2020-05-02T15:01:32Z\"\n    \"name\" = \"default\"\n    \"resourceVersion\" = \"147\"\n    \"selfLink\" = \"/api/v1/namespaces/default\"\n    \"uid\" = \"6ac3424c-07a4-4a69-86ae-cc7a4ae72be3\"\n  }\n  \"spec\" = {\n    \"finalizers\" = [\n      \"kubernetes\",\n    ]\n  }\n  \"status\" = {\n    \"phase\" = \"Active\"\n  }\n}
\n

Convert a Helm chart to Terraform

\n

You can use helm template to generate a manifest from the chart, then pipe it into tfk8s:

\n
helm template ./chart-path -f values.yaml | tfk8s\n
\n

Convert a directory tree of manifests to Terraform

\n

You can use tfk8s in conjunction with find to convert an entire directory recursively:

\n
find dirname/ -name '*.yaml' -type f -exec sh -c 'tfk8s -f {} -o $(echo {} | sed \"s/\\.[^.]*$//\").tf' \\;
