Upgrading to CDK for Terraform Version 0.11

0.11 includes improvements to the provider code bindings, to allow referencing maps of computed attributes as a whole map instead of just individual items of that map. Both lists and maps now allow accessing all computed attributes of an assignable property. More control over logging was also added.

TF_VAR_ prefixed environment variables can no longer be accessed at synth time

These environment variables will now be filtered out in the synth phase since they are only intended to be used during diff (plan) and deploy (apply) phases to supply values for TerraformVariables. This inhibits accidentally inlining those values into the generated cdk.tf.json config.

Environment variable and CLI option changes

• DEBUG is replaced by setting CDKTF_LOG_LEVEL=debug, setting the CDKTF_LOG_LEVEL to debug will now also behave like DEBUG=1 and include logs from the provider generation
• CDKTF_DISABLE_LOGGING=false is replaced by setting CDKTF_LOG_FILE_DIRECTORY=/path/to/logs/directory. If left empty no logs will be written.
• --disable-logging was removed, instead use the environment variable CDKTF_LOG_LEVEL=off
• DISABLE_VERSION_CHECK, CDKTF_DISABLE_PLUGIN_CACHE_ENV need to be set to true or 1, before anything worked.

Stack ids can no longer contain whitespaces

A TerraformStack may no longer contain whitespace characters, since we rely on paths being whitespace free. If you have a stack with an id containing a whitespace, please replace it with a hyphen. If the stack was already deployed with the default LocalBackend you might need to rename your statefile to match the new stack id.

Computed Map References are referenced through getter

For computed maps, the reference is now through a getter.

To access { property = "value" }, instead of resource.mapAttribute("property") you can now use resource.mapAttribute.lookup("property").

Example

const bucket = new s3.S3Bucket(this, "bucket");

// previously
const firstRuleStage = bucket.lifecycleRule.get(0).tags("stage");
const firstRuleTags = bucket.get(0).interpolationForAttribute("tags");

// new
const firstRuleStage = bucket.lifecycleRule.get(0).tags.lookup("stage");
const firstRuleTags = bucket.lifecycleRule.get(0).tags;

Use ComplexLists and ComplexMaps for complex assignable properties

PR: #1725

Assignable properties of the form Object[] or { [key: string]: Object } no longer have setters; they instead have putX methods. The getter return type is also changed to be a derivative of either ComplexList or ComplexMap.

Typescript

// previously
list.req = ["value"];
Fn.lookup(Fn.element(list.req, 0), "reqstr", "default");

// new
list.putReq(["value"]);
list.req.get(0).reqstr;

Python

# previously
list.req = ["value"]
Token().as_string(Fn.lookup(Fn.element(list.req, 0), "reqstr", "default"))

# new
list.put_req(["value"])
list.req.get(0).reqstr

CSharp

// previously
list.Req = new [] {"value"}
Token.AsString(Fn.Lookup(Fn.Element(list.Req, 0), "reqstr", "default"))

// new
list.PutReq(new [] {"value"})
list.Req.Get(0).Reqstr

Java

// previously
list.setReq(new string[] {"value"})
Token.asString(Fn.lookup(Fn.element(list.getReq(), 0), "reqstr", "default"))

// new
list.putReq(new string[] {"value"})
list.getReq().get(0).getReqstr()

Go

// previously
list.Req(&[]*string{jsii.String("value"}))
cdktf.Token_AsString(cdktf.Fn_Lookup(cdktf.Fn_Element(list.Req(), jsii.Number(0)), jsii.String("reqstr"), jsii.String("default")))

// new
list.PutReq(&[]*string{jsii.String("value"}))
list.Req().Get(jsii.Number(0)).Reqstr()
