Example does not work: ReferenceError

[kklepper]

Hello, as far as I can see your example should work out of the box, but it doesn't.

What did I do?

I put example.js to the root directory, made a subdirectory output from there and started your instruction:

# echo example.js | docker run -i --rm --security-opt seccomp=$HOME/chrome.json \
>     --mount type=bind,source="$(pwd)"/output,target=/output \
>     --name puppeteer-headless \
>     justinribeiro/puppeteer-headless \
>     node -e "`cat $_`"
[eval]:1
example.js
^

ReferenceError: example is not defined
    at [eval]:1:1
    at ContextifyScript.Script.runInThisContext (vm.js:50:33)
    at Object.runInThisContext (vm.js:139:38)
    at Object.<anonymous> ([eval]-wrapper:6:22)
    at Module._compile (module.js:653:30)
    at evalScript (bootstrap_node.js:479:27)
    at startup (bootstrap_node.js:180:9)
    at bootstrap_node.js:625:3

Unfortunately, I cannot debug this by myself. What am I doing wrong? Can you help me?

Explanation

I have a docker puppeteer container with node myself and it works, I am just curious to test with your container as I stumbled upon a recommendation somewhere.

My container use has to be throttled somewhat as CPU tends to rise when too many parallel requests are running. I suppose this is perfectly normal, but maybe your solution works better.
