Answer 1

Basically, it can't find the iamdenmarkcontrevida/base image in dockerhub.

Did you build/push the base image?

docker build .
docker tag <local-image-id> iamdenmarkcontrevida/base:latest
docker push iamdenmarkcontrevida/base

Answer 2

No need push, if you only need run it locally.

So you need build the base image first, then build actinbox3.2

For example (suppose you have different Dockerfile name)

sudo docker build -t iamdenmarkcontrevida/base -f Dockerfile.base
sudo docker build -t actinbox3.2 -f Docker.actinbox3.2

tag latest is default, so no need add it in build command.

Answer 3

You can try packer framework
that is easiest way to create docker image. it also supported many other type of machine image.

https://www.packer.io/docs/builders/index.html

Answer 4

It's just a two line command -

1. Get your local-image-id

docker ps

2. Copy Names

docker build -t local-image-id/Any name you want:latest . 

For me docker build -t condescending_greider/newdoc:latest .

Thanks for your time :)
