Docker les. We'll be focusing on WORKDIR, ENV, ADD, and ENTRYPOINT.

WORKDIR /path/to/workdir
The WORKDIR instruction sets the working directory for any RUN , CMD and ENTRYPOINT instructions
that follow it in the Dockerfile .
It can be used multiple times in the one Dockerfile . If a relative path is provided, it will be relative
to the path of the previous WORKDIR instruction. For example:
WORKDIR /a
WORKDIR b
WORKDIR c
RUN pwd
The output of the nal pwd command in this Dockerfile would be /a/b/c.
The WORKDIR instruction can resolve environment variables previously set using ENV . We can only
use environment variables explicitly set in the Dockerfile . For example:
ENV DIRPATH /path
WORKDIR $DIRPATH/$DIRNAME
The output of the nal pwd command in this Dockerfile would be /path/$DIRNAME .
ENV <key> <value>
The ENV instruction sets the environment variable <key> to the value <value>. This value will be
passed to all future RUN instructions. This is functionally equivalent to pre xing the command with
<key>=<value>
The environment variables set using ENV will persist when a container is run from the resulting
image. We can view the values using docker inspect , and change them using
docker run --env <key>=<value> .
Note: One example where this can cause unexpected consequences, is setting
ENV DEBIAN_FRONTEND noninteractive. Which will persist when the container is run interactively; for
example: docker run -t -i image bash .

Here we're using repository name (tag) for the image, and the dot('.') indicates our Docker le is in
local directory.
What images do we have now?
Note the images tagged with <none>. These are the images which had no tag, and left behind when
a new image is tagged as 'latest'.
Now we're going to run a new container and run bash inside of it:
$ docker run -it --rm bogodevops/demo /bin/bash
We can check the WORKDIR and ENV settings in our Dockerfile :
$ docker build -t bogodevops/demo .

OK. We've got what we expected.
Docker e - ADD
ADD <src>... <dest>
The ADD instruction copies new les, directories or remote le URLs from <src> and adds them to
the lesystem of the container at the path <dest>.
Multiple <src> resource may be speci ed but if they are les or directories then they must be
relative to the source directory that is being built (the context of the build).
Each <src> may contain wildcards and matching will be done using Go's filepath.Match rules. For
most command line uses this should act as expected, for example:
ADD hom* /mydir/ # adds all files starting with "hom"
ADD hom?.txt /mydir/ # ? is replaced with any single character
The <dest> is the absolute path to which the source will be copied inside the destination container.

An ENTRYPOINT allows us to con gure a container that will run as an executable.
For example, the following will start nginx with its default content, listening on port 80:
docker run -i -t --rm -p 80:80 nginx
Command line arguments to docker run <image> will be appended after all elements in an exec
form ENTRYPOINT , and will override all elements speci ed using CMD . This allows arguments to be
passed to the entry point, i.e., docker run <image> -d will pass the -d argument to the entry point.
We can override the ENTRYPOINT instruction using the docker run --entrypoint ag.
Here is our updated Dockerfile which includes ENTRYPOINT :
FROM debian:latest
# 1 - RUN
RUN apt-get clean
# 2 - CMD
#CMD ["htop"]
#CMD ["ls", "-l"]
WORKDIR /root
ENV DZ version1
# 4 - ADD

Container run without any argument:
$ docker run -it --rm bogodevops/demo
There are 1 arguments: arg1
It still runs run.sh shell. If we pass in something like /bin/bash :
$ docker run -it --rm bogodevops/demo /bin/bash
There are 1 arguments: /bin/bash
Still it runs run.sh le while /bin/bash was passed in as an argument.
