Pipeline Syntax. Differences when considering top and stage level Agents
Available Stage Options
Skip looking into rule from source control by standard within the agent directive. For instance: choices
Set a timeout duration with this phase, after which it Jenkins should abort the phase. For instance: choices
This stage the specified number of times on failure, retry. For instance: options
Prepend all system production generated in this phase with all the right time of which the line ended up being emitted. As an example: choices
The parameters directive provides a summary of parameters that a person should offer whenever triggering the Pipeline. The values for those user-specified parameters are distributed around Pipeline actions through the params object, begin to see the Parameters, Declarative Pipeline for the certain use.
Only one time, within the pipeline block.
A parameter of the sequence kind, as an example: parameters
A text parameter, that could contain lines that are multiple as an example: parameters
A boolean parameter, as an example: parameters
A selection parameter, for instance: parameters
A password parameter, as an example: parameters
A list that is comprehensive of parameters is pending the conclusion of INFRA-1503.
The causes defines that are directive automated ways that the Pipeline should be re-triggered. For Pipelines that are incorporated with a supply such as for instance GitHub or BitBucket, triggers may possibly not be necessary as webhooks-based integration will most likely currently be there. The causes now available are cron , pollSCM and upstream .
Just once, within the pipeline block.
Accepts a string that is cron-style define a consistent period of which the Pipeline must be re-triggered.
Accepts a cron-style sequence to define a frequent period at which Jenkins should search for brand brand brand new supply modifications. If brand brand new modifications occur, the Pipeline will undoubtedly be re-triggered.
Accepts a comma-separated sequence of jobs and a limit. Whenever any working work within the sequence completes utilizing the minimum limit, the Pipeline will likely be re-triggered. As an example: causes
The pollSCM trigger is for sale in Jenkins 2.22 or later on.
Jenkins cron syntax
The syntax of this cron energy (with small distinctions). Specifically, each line consist of 5 industries divided by TAB or whitespace:
Minutes inside the full hour(0РІР‚вЂњ59)
The hour of the(0РІР‚вЂњ23 day)
The time associated with thirty days (1РІР‚вЂњ31)
The thirty days (1РІР‚вЂњ12)
The of the week (0РІР‚вЂњ7) where 0 and 7 are Sunday day.
To specify multiple values for just one industry, the next operators can be obtained. In the near order of precedence,
* specifies all legitimate values
M-N specifies a variety of values
M-N/X or */X actions by periods of X through the specified range or entire range that is valid
A,B,вЂ¦вЂ‹,Z enumerates values that are multiple
To permit sporadically planned tasks to create even load on the machine, the expression H (for РІР‚СљhashРІР‚Сњ) must be utilized whenever we can. For instance, utilizing 0 0 * * * for a dozen day-to-day jobs can cause a big increase at midnight. In comparison, making use of H H * * * would nevertheless perform each work as soon as per day, not all during the time that is same better utilizing restricted resources.
The H icon could be regarded as a range, however it happens to be a hash associated with the work title, maybe not really a random function, so the value continues to be stable for just about any offered task.
The stage directive goes into the phases part and may have a actions area, an agent that is optional, or any other stage-specific directives. Virtually talking, all the work that is real with a Pipeline should be wrapped in a number of phase directives.
One mandatory parameter, a sequence for the title associated with phase.
In the phases area.
A area defining tools to put and auto-install in the PATH . This is certainly ignored if representative none is specified.
In the pipeline block or perhaps a phase block.
