Docker
Why do we need to keep an eye on the docker layers in the dockerfile?
Every docker container starts from the
instruction written
in the dockerfile.
But writing random keywords in dockerfile itself does not create an
effective container
.
The primary goal of writing a docker file is to make the
docker containers as lightweight as possible
.
The first step to make the container lighter is to use the
lighter base image.
The other important factor is to
minimise
the docker layers
.
The layer in a dockerfile is the
intermediate image
created when an image is built.
Each layer
represents an instruction
in the Dockerfile image.
To minimise the layers try
to club the similar keywords
together.
