node:10-alpine different node version from docs

[dyihoon90]

I ran docker pull node:10-alpine and then docker run -it. The node version in the image is v10.15.1. According to the docs the dockerfile should be 10.16.3.

Would someone help look into this? Thank you very much.

You probably have an old image cached locally

urgh.. what an oversight on my side. Thank you for addressing this @SimenB

@SimenB we looked into this deeper again today, and it looks to be related to content trust at the Docker hub registry rather than local cache.

With export DOCKER_CONTENT_TRUST=1,
docker pull node:10-alpine node version is v10.15.1, image ID fe6ff768f798

With export DOCKER_CONTENT_TRUST=0,
docker pull node:10-alpine node version is v10.16.3, image ID b95baba1cfdb

$ docker info | grep Registry
Registry: https://index.docker.io/v1/

That would be tracked in #1065
