2. Click on the icon for the Quickstart Terminal window to launch it from the Application/Docker folder. Verify the installation by running the hello-world container.
$docker - run hello-world

- git clone https://opensource.ncsa.illinois.edu/bitbucket/scm/bd/path/to/template_converter.git
- Or, Download the template project from the repository: https://opensource.ncsa.illinois.edu/bitbucket/projects/BD/repos/path/to/templatemplatetemplate_converter
The template-converter directory consists of one file (docker-compose.yml), and one sub-directory, example-server , with two files: Dockerfile and ImageMagick_convert.sh.
...
Step 4: Testing the example-server
- Open another docker terminal
Open Kitematic, press button 'DOCKER CLI' in bottom-left corner
- Change to the example-server directory:
...
- Make sure the permission for ImageMagick_convert.sh is 755.
$cd chmod $chmod 755 ImageMagick_convert.sh
- Build and launch the example software server with the converter
$docker build –t -t example-server .
$docker run --rm -t -i --link polyglotimageconverter_rabbitmq_1:rabbitmq example-server
...
- Modify the MyTool_convert.sh using any editor (e.g. vim). A simple example is shown below:
...
| Code Block | ||||||
|---|---|---|---|---|---|---|
| ||||||
#!/bin/sh |
...
#ImageMagick (v6.5.2) |
...
#image |
...
#png bmp foobar |
...
#jpg output_filename=$(basename "$2") |
...
output_format="${output_filename##*.}" |
...
#Output PGM files as ASCII if [ "$output_format" = "pgm" ]; then |
...
convert "$1" -compress none "$2" |
...
else convert "$1" "$2" |
...
fi |
Line 2 : Change ImageMagick to MyTool
...
- To build, launch and test the new converter, run the following command:
$docker build –t mytool .
$docker run --rm -t -i --link polyglot_rabbitmq_1:rabbitmq mytool
