What error do you get?

Inside sandbox, with `./sandbox enter`, I can do:

```auto
algorand@1116903d7142:/opt/algorand/node$ echo "// simple.teal
// Do not use this in a real application
int 0" > simple.teal

algorand@1116903d7142:/opt/algorand/node$ goal clerk compile simple.teal
simple.teal: KI4DJG2OOFJGUERJGSWCYGFZWDNEU2KWTU56VRJHITP62PLJ5VYMBFDBFE

algorand@1116903d7142:/opt/algorand/node$ ls simple.teal*
simple.teal simple.teal.tok

```

You can transfer files between sandbox and the outside as follows:

```auto
docker cp sandbox:/opt/algorand/node/simple.teal.tok simple.teal.tok

```
