Any other conditions are required of docker?

ubuntu16.04 Docker version 17.03.1-ce, build c6d412e

When I tried

docker exec bot-render-container curl http://localhost:8080/?url=https://dynamic-meta.appspot.com

docker console output following logs

Did you build with the --no-cache flag?

[samuelli]

See also #2 which they required --disable-sandbox

I confirm the same problem on MacOS. I solved the problem adding the --disable-sandbox flag within the chromium.js file.

Maybe this should be written on the README 👍

[samuelli]

Yup, will do. Interestingly the original issue here was on Ubuntu, so I'm curious as to whether its the same problem. @Raxxor: does this fix it for you?

Thanks for @samuelli & @LasaleFamine 's comments.
Docker was built by dockerhub, so it is buit with "no cache" mode. Now I am pulling images from dockerhub with adding "--disable-sandbox' in chromium.js.
BTW, i tried to run original files , and some pages was not rendered successfully.

@justinribeiro has landed added some great recommendations to the readme which address this, so I'm closing this issue. Please file issues for more errors that you might be experiencing.

@Raxxor: can you file separate issues for anything else you might be seeing?

I'm on MacOS sierra and get { message: 'net::ERR_CONNECTION_REFUSED' } whenever I try to render or screenshot the tour of heroes project launching with ng serve
I checked and tried the suggestions at https://github.com/GoogleChrome/rendertron#connection-error-econnrefused but none of them works.
Could you please suggest where should I add the --disable-sandbox flag to?

I have done following commands:

git clone https://github.com/GoogleChrome/rendertron.git server
cd server

docker build -t rendertron . --no-cache=true

docker run -it -p 8080:8080 --name rendertron-container rendertron
