What are Machine images?
A Machine image is an pre-baked image that contains all the necessary components installed to run your CI (
runSh jobs. Every
Subscription (org/team depending on SCM you use) has a default version of the machine image configured. This default is setup whenever the first
CI or Assembly Line is enabled on Shippable.
The following picture shows the components of the machine image and how they interact with each other.
- When a new job is triggered, Shippable orchestration spins up a new build node, aka minion, with your default Subscription machine image.
- For CI jobs configured with
shippable.yml, the Shippable Agent on the build node spins up a build container using either the default Docker image depending on the
languagetag in your yml configuration or a custom Docker image if specified in the yml. All commands in the
post_cisection of your YAML are run inside the build container.
runShjobs configured in
shippable.yml, commands in the
scriptsection are run in the Shippable Agent.
We currently offer the following Machine Images. The default Machine Image for your subscription is the latest image available when your Subscription was added to Shippable.
You can click on any image below to see what is pre-installed:

In most cases, the default Machine image set for your Subscription will be sufficient to run your builds. The main reasons why you might want to consider changing to a more recent image are:
- You need a newer language/service/package version
- You need a newer Docker version
