Can we build a docker image using .tar or zip archive

Question

Can we build a docker image using tarball or zip archive which includes dockerfile inside that. I need to build a image from archives by using docker api. Is there any reference or resource , I have search for 3o minutes but couldn't find anything. Help me, please! Thanks in advance!

Accepted Answer

yes a dockerimage can be build from a tarball containing the `Dockerfile`. Let's assume we have a dockerfile called `myDockerfile` which contains the following scripts

```
FROM ubuntu

COPY ./venv /

CMD ["/bin/bash"]
```

`myDockerFile` is present inside the folder `dockerfiles`

```
FOLDER --> dockerfiles
FILE   -----------> myDockerFile 
```

the tarball for folder `dockerfiles` is called `dockerfiles.tar`

the docker command to build the image will be:-

```
cat dockerfiles.tar | docker build - -f dockerfiles/myDockerFile -t mydockerimage
```

note:-

```
-f denotes the docker file in context to the tarball , if the dockerfile is called 'Dockerfile'
then there is no need to mention the name of the filename verbose
```
