'Where does docker get the node version from?

In the Dockerfile I have specified the node:14.17.6-alpine3.13 version. In the deploy log the following version appears node:16.13.2-alpine. Does anyone know what is the reason for this? Or where to change this?

docker-compose deploy log:

Solution 1:^[1]

This line docker_nestjs-backend development , shows that docker_nestjs-backend throws the error. You can change that to required configuration.
