What is Perl?
Perl is a high-level, general-purpose, interpreted, dynamic programming language. The Perl language borrows features from other programming languages, including C, shell scripting (sh), AWK, and sed.
How to use this image
Dockerfile in your Perl app project
FROM i386/perl:5.20 COPY . /usr/src/myapp WORKDIR /usr/src/myapp CMD [ "perl", "./your-daemon-or-script.pl" ]
Then, build and run the Docker image:
$ docker build -t my-perl-app . $ docker run -it --rm --name my-running-app my-perl-app
Run a single Perl script
For many simple, single file projects, you may find it inconvenient to write a complete
Dockerfile. In such cases, you can run a Perl script by using the Perl Docker image directly:
$ docker run -it --rm --name my-running-script -v "$PWD":/usr/src/myapp -w /usr/src/myapp i386/perl:5.20 perl your-daemon-or-script.pl
Example: Creating a reusable Carton image for Perl projects
FROM i386/perl:5.26 RUN cpanm Carton \ && mkdir -p /usr/src/app WORKDIR /usr/src/app ONBUILD COPY cpanfile* /usr/src/myapp ONBUILD RUN carton install ONBUILD COPY . /usr/src/app
Then, in your Carton project, you can now reduce your project's
Dockerfile into a single line of
FROM i386/perl:carton, which may be enough to build a stand-alone image.
Having a single
i386/perl:carton base image is useful especially if you have multiple Carton-based projects in development, to avoid "boilerplate" coding of installing Carton and/or copying the project source files into the derived image. Keep in mind, though, about certain things to consider when using the Perl image in this way:
- This kind of base image will hide the useful bits (such as the
RUNabove) in the image, separating it from more specific Dockerfiles using the base image. This might lead to confusion when creating further derived images, so be aware of how ONBUILD triggers work and plan appropriately.
- There is the cost of maintaining an extra base image build, so if you're working on a single Carton project and/or plan to publish it, then it may be more preferable to derive directly from a versioned
i386/perl images come in many flavors, each designed for a specific use case.
This is the defacto image. If you are unsure about what your needs are, you probably want to use this one. It is designed to be used both as a throw away container (mount your source code and start the container to start your app), as well as the base to build other images off of.
This tag is based off of
buildpack-deps is designed for the average user of Docker who has many images on their system. It, by design, has a large number of extremely common Debian packages. This reduces the number of packages that images that derive from it need to install, thus reducing the overall size of all images on your system.
This image does not contain the common packages contained in the default tag and only contains the minimal packages needed to run
i386/perl. Unless you are working in an environment where only the
i386/perl image will be deployed and you have space constraints, we highly recommend using the default image of this repository.
