Terraform
jsonencode Function
jsonencode encodes a given value to a string using JSON syntax.
The JSON encoding is defined in RFC 7159.
This function maps Terraform language values to JSON values in the following way:
| Terraform type | JSON type |
|---|---|
string | String |
number | Number |
bool | Bool |
list(...) | Array |
set(...) | Array |
tuple(...) | Array |
map(...) | Object |
object(...) | Object |
| Null value | null |
Since the JSON format cannot fully represent all of the Terraform language
types, passing the jsonencode result to jsondecode will not produce an
identical value, but the automatic type conversion rules mean that this is
rarely a problem in practice.
When encoding strings, this function escapes some characters using
Unicode escape sequences: replacing <, >, &, U+2028, and U+2029 with
\u003c, \u003e, \u0026, \u2028, and \u2029. This is to preserve
compatibility with Terraform 0.11 behavior.
The jsonencode command outputs a minified representation of the input.
Examples
> jsonencode({"hello"="world"})
{"hello":"world"}
