Docker-compose on Torizon


The docker command works well for our single container application. We’re trying to run multi container app with docker-compose. However, docker-compose repose with the error below. How can this be fixed?
Tnx, Dov

Greetings @dovz11,

This is a known issue that has been resolved in the latest TorizonCore release which has just been recently made public. Please use the Toradex Easy Installer to flash the latest TorizonCore.

Best Regards,

Hi @jeremias.tx

Thank you. I have used the Toradex easy installer to install the existing Torizon OS. Can you please point me to the instructions for relaunching the installer as the system now boots directly to Torizon?


Hi @dovz11,

Please refer to: Downloads & Installers | Toradex Developer Center

This page will show you how to put your module into recovery mode then load the easy installer.

Hi @jeremias.tx

Thanks. I went through the [non trivial…] process, upgraded the os and got docker-compose to work.

Perfect. Thanks for the feedback.
