Action Handler: Shell Script

ID: com.fireblink.fbl.shell
Aliases:
  • fbl.shell
  • shell
Example:
shell:
# shell executable
executable: '/bin/bash'
# script to be invoked
script: |-
cd /tmp
touch test.txt
# [optional] working directory to run script from.
# Default value: flow's folder
wd: <%- cwd %>
# [optional] options
options:
# [optional] if provided "stdout" will be included inside assigned object to proviced "ctx" and/or "secrets" name
stdout: true
# [optional] if provided "stderr" will be included inside assigned object to proviced "ctx" and/or "secrets" name
stderr: true
# [optional] if provided - stdout and stderr will be logged in report and printed to console

# [optional] assign execution result {code: 0-255, stdout?: string, stderr?: string }
assignResultTo: # follows common assignment logic practicies https://fbl.fireblink.com/plugins/common#assign-to
# [optional] push execution result {code: 0-255, stdout?: string, stderr?: string }

Action Handler: Function

Allows to invoke custom JavaScript script (ES6). Script has access to all context variables:
  • cwd
  • ctx
  • secrets
  • parameters
  • iteration
But also to Node.js require function and can interact with awailable node modules. Though, it is recomended to use fbl plugins instead.
ID: com.fireblink.fbl.function
Aliases:
  • fbl.function
  • function
  • function()
  • fn
  • fn()
Example: Direct Changes
# Action handler expects valid JS function content string.
#
# Note: script is wrapped into async function, so you can "await" promises inside it
# if you need to do some long running operations.
fn: |-
ctx.isWindows = require('os').platform() === 'win32';
Example: Overrides
Alternativelly function can return object that will be used to override entire state of context and parameters fields.
fn: |-
return {
cwd: '/tmp',
ctx: {
test: true
}
}
fn: |-
return {
secrets: {
test: true
},
parameters: {
p1: ctx.p2
}
}
