# Ruby 3.3 Container Image
|
||
|
|
|
||
|
|
|
||
|
|
|
||
|
|
## Description
|
||
|
|
|
||
|
|
[Ruby](https://www.ruby-lang.org/) is a dynamic, reflective, object-oriented, general-purpose, open-source programming language. It supports multiple programming paradigms, including functional, object-oriented, and imperative. It also has a dynamic type system and automatic memory management.
|
||
|
|
|
||
|
|
## Usage
|
||
|
|
|
||
|
|
To deploy an application, install dependencies, copy the sources, and configure the application's main script:
|
||
|
|
|
||
|
|
```Dockerfile
|
||
|
|
FROM registry.opensuse.org/opensuse/bci/ruby:3.3
|
||
|
|
|
||
|
|
# displays an error message if Gemfile and Gemfile.lock are not in sync
|
||
|
|
RUN bundle config --global frozen 1
|
||
|
|
|
||
|
|
WORKDIR /app
|
||
|
|
|
||
|
|
COPY Gemfile Gemfile.lock ./
|
||
|
|
RUN bundle install
|
||
|
|
|
||
|
|
COPY . .
|
||
|
|
|
||
|
|
CMD [ "ruby", "./main-script.rb" ]
|
||
|
|
```
|
||
|
|
|
||
|
|
Build and run the container image:
|
||
|
|
|
||
|
|
```ShellSession
|
||
|
|
$ podman build -t my-ruby-app .
|
||
|
|
$ podman run -it --rm my-ruby-app
|
||
|
|
```
|
||
|
|
|
||
|
|
The example above assumes that there is a `Gemfile.lock` file in the application directory.
|
||
|
|
To generate a `Gemfile.lock` file, use the following command:
|
||
|
|
|
||
|
|
```ShellSession
|
||
|
|
$ podman run --rm -v "$PWD":/app:Z -w /app registry.opensuse.org/opensuse/bci/ruby:3.3 bundle lock
|
||
|
|
```
|
||
|
|
|
||
|
|
To run a single script inside a container, use the following command:
|
||
|
|
|
||
|
|
```ShellSession
|
||
|
|
$ podman run --rm -v "$PWD":/app:Z -w /app registry.opensuse.org/opensuse/bci/ruby:3.3 ruby script.rb
|
||
|
|
```
|
||
|
|
|
||
|
|
## Encoding
|
||
|
|
|
||
|
|
The Ruby image sets the locale environment variable `LANG` to `C.UTF-8`.
|
||
|
|
|
||
|
|
## Additional tools
|
||
|
|
|
||
|
|
In addition to the standard SLE BCI development packages the following
|
||
|
|
additional tools are included in the image:
|
||
|
|
|
||
|
|
- gcc-c++
|
||
|
|
- make
|
||
|
|
- sqlite3-devel
|
||
|
|

|
||
