spikepy / bash-file-templating

Usage

1. Make the file tempalte-file executable by running chmod +x template-file
2. Move it to a directory in your $PATH or call it directly
3. Run the script with your variables file as argument 1 and your template files as cosecutive arguments

• The template filename should include the expected file extension appended with '.template'
• You can call tempalte-file with multiple files as arguments, this means they will share the same values
• you can use wildcards in the arguments as your shell resolves them before the script is executed
• if you want to use multiple variable files you could source another variable file from within the argument-1-variables file

6. The templated result will be stored in your PWD

Variable File

Define you variables in this file just like you define bash variables (this also enables you to use bashs string manipulation). You can also use commands as values for variables e.g. EXAMPLE_DATE=$(date)

Template File

Write your template as normal text file. Use bash variables e.g. ${USER} for templating (bash string manipulation is also possible). You can even use commands e.g. $(date).

Example

cd examples
template-file variables.sh example_static_pod.yaml.template
