Simple YAML declarative shell scripting language based on modules and templates.
rash
syntax is inspired by Ansible.
Quickstart
To start using rash
you just need a container with entrypoint.
For install, add rash
binary to your Dockerfile:
FROM ghcr.io/rash-sh/rash AS rash
FROM nginx
COPY --from=rash /bin/rash /bin
COPY entrypoint.rh /
ENTRYPOINT ["/entrypoint.rh"]
Also, you must create your first entrypoint.rh
:
#!/bin/rash
- copy:
content: |
server {
listen 80;
{% for domain in env.DOMAINS | split(',') -%}
{% set path = domain | split('.') | first -%}
location /{{ path }} {
rewrite /{{ path }}[/]?(.*) /$1 break;
proxy_pass http://{{ domain }};
}
{% endfor %}
}
dest: /etc/nginx/conf.d/default.conf
- command:
argv: [nginx, '-g', 'daemon off;']
transfer_pid: true
Or instead, you could want to use rash
for local scripting. In that case you can follow
our installation guide.
Syntax
YAML syntax based on modules.
Besides, rash
includes MiniJinja templates which you can use
anywhere. You can use all its functions and combine them as you want.
rash
implements custom builtins, too. For example, {{ rash.path }}
or
{{ env.MY_ENV_VAR }}
.
