+# Perl S2I
+This repository contains the sources for S2I builder image for perl 5.24 as well as some sample applications. This is a port to Fedora of software collections Perl located [here](https://github.com/sclorg/s2i-perl-container), that is now using base-runtime and Perl module. Please note that this solution uses httpd 2.4 to display results. 
+
+# Usage 
+## Docker
+First you need to build the builder image. After you have the builder image, you can use it for a S2I build. You can build and run the sample app like this:
+```
+$ docker build --tag=koscicz/perl .
+$ s2i build https://github.com/container-images/perl.git --context-dir=test/sample-test-app/ koscicz/perl perl-sample-app
+$ docker run -p 8080:8080 perl-sample-app
+```
+This will build and run you application on 127.0.0.1:8080. You can also build the builder image by running `make`. This will also tag your image as koscicz/perl.
+
+## Openshift
+You can use the `openshift-template.yml` in this repository to run your application in Openshift. You can either use web interface, in which case you'll just have to fill out a form, requiring a source repository for your app and name of this app. In case you want to use cli, you can do it like this, after you login:
+```
+$ oc new-project perl-test
+$ oc new-app https://raw.githubusercontent.com/container-images/perl/master/openshift-template.yml -p APP_NAME="perl-example" -p SOURCE_REPOSITORY="https://github.com/kosciCZ/perl-example"
+```
+These commands will build the sample application on your Openshift platform.
+
+# Testing
+This repository contains a `test` folder with some tests to ensure proper functionality. You can run test by using Makefile. You have two options:
+* `make all` This will build, tag and test the image
+* `make test` This will run the test on the image, that is defined in the Makefile. By default it is koscicz/perl
+Or you can execute the test script directly, as described below in [Repository organization](#repository-organization)
+
+Repository organization
+------------------------
+* **Dockerfile**
+
+    Fedora based Dockerfile.
+
+* **`s2i/bin/`**
+
+    This folder contains scripts that are run by [S2I](https://github.com/openshift/source-to-image):
+
+    *   **assemble**
+
+        Used to install the sources into a location where the application
+        will be run and prepare the application for deployment (eg. installing
+        modules, etc.).
+        In order to install application dependencies, the application must contain a
+        `cpanfile` file, in which the user specifies the modules and their versions.
+        An example of a [cpanfile](https://github.com/container-images/perl/blob/master/test/sample-test-app/cpanfile) is available within our test application.
+
+        All files with `.cgi` and `.pl` extension are handled by mod_perl.
+        If exactly one file with `.psgi` extension exists in the top-level
+        directory, the mod_perl will be autoconfigured to execute the PSGI
+        application for any request URI path with Plack's mod_perl adaptor.
+
+    *   **run**
+
+        This script is responsible for running the application, using the
+        Apache web server.
+
+    *   **usage***
+
+        This script prints the usage of this image.
+
+* **`contrib/`**
+
+    This folder contains a file with commonly used modules.
+
+* **`test/`**
+
+	This folder contains some sample applications you can use to test you image.
+
+    * **`sample-test-app/`**
+
+        A simple Perl application used for testing purposes by the [S2I](https://github.com/openshift/source-to-image) test framework.
+
+    * **run**
+
+        This is a script that runs a test suite on the builder image, to ensure it has all the necessary functionality.
+        Run it by `./run IMAGE`, where `IMAGE` is your builder image.
+
+Environment variables
+---------------------
+
+To set environment variables, you can place them as a key value pair into a `.sti/environment`
+file inside your source code repository.
+
+* **ENABLE_CPAN_TEST**
+
+    Allow the installation of all specified cpan packages and the running of their tests. The default value is `false`.
+
+* **CPAN_MIRROR**
+
+    This variable specifies a mirror URL which will used by cpanminus to install dependencies.
+    By default the URL is not specified.
+
+* **PERL_APACHE2_RELOAD**
+
+    Set this to "true" to enable automatic reloading of modified Perl modules.
+
+* **HTTPD_START_SERVERS**
+
+    The [StartServers](https://httpd.apache.org/docs/2.4/mod/mpm_common.html#startservers)
+    directive sets the number of child server processes created on startup. Default is 8.
+
+* **HTTPD_MAX_REQUEST_WORKERS**
+
+    Number of simultaneous requests that will be handled by Apache. The default
+    is 256, but it will be automatically lowered if memory is limited.
+
+* **PSGI_FILE**
+
+    Override PSGI application detection.
+
+    If the PSGI_FILE variable is set to empty value, no PSGI application will
+    be detected and mod_perl not be reconfigured.
+
+    If the PSGI_FILE variable is set and non-empty, it will define path to
+    the PSGI application file. No detection will be used.
+
+    If the PSGI_FILE variable does not exist, autodetection will be used:
+    If exactly one ./*.psgi file exists, mod_perl will be configured to
+    execute that file.
+
+* **PSGI_URI_PATH**
+
+    This variable overrides location URI path that is handled path the PSGI
+    application. Default value is "/".

+Script for parsing cgroup information
+
+This script will read some limits from the cgroup system and parse
+them, printing out "VARIABLE=VALUE" on each line for every limit that is
+successfully read. Output of this script can be directly fed into
+bash's export command. Recommended usage from a bash script:

+        currently constant value of 9223372036854775807.
+    MEMORY_LIMIT_IN_BYTES
+        Maximum amount of user memory in bytes. If this value is set
+        to the same value as MAX_MEMORY_LIMIT_IN_BYTES, it means that
+        there is no limit set. The value is taken from
+        /sys/fs/cgroup/memory/memory.limit_in_bytes

+PERL\_APACHE2\_RELOAD
+
+    Set this to "true" to enable automatic reloading of modified Perl modules.
+
+HTTPD\_START\_SERVERS
+
+    The [StartServers](https://httpd.apache.org/docs/2.4/mod/mpm_common.html#startservers)
+    directive sets the number of child server processes created on startup. Default is 8.
+
+HTTPD\_MAX\_REQUEST\_WORKERS
+
+    Number of simultaneous requests that will be handled by Apache. The default
+    is 256, but it will be automatically lowered if memory is limited.
+
+PSGI_FILE
+
+    Override PSGI application detection.
+
+    If the PSGI_FILE variable is set to empty value, no PSGI application will
+    be detected and mod_perl not be reconfigured.
+
+    If the PSGI_FILE variable is set and non-empty, it will define path to
+    the PSGI application file. No detection will be used.
+
+    If the PSGI_FILE variable does not exist, autodetection will be used:
+    If exactly one ./*.psgi file exists, mod_perl will be configured to
+    execute that file.
+
+PSGI\_URI\_PATH
+
+    This variable overrides location URI path that is handled path the PSGI
+    application. Default value is "/".
