Under `MachineOptions` you can add anything that the [AWS Docker Machine driver
supports](https://docs.docker.com/machine/drivers/aws/#options).

### `[runners.cache]`
To speed up your jobs, GitLab Runner provides a cache mechanism where selected
directories and/or files are saved and shared between subsequent jobs.
While not required for this setup, it is recommended to use the shared cache
mechanism that GitLab Runner provides. Since new instances will be created on
demand, it is essential to have a common place where cache is stored.
In the following example, we use Amazon S3:
```
toml
[runners.cache]
Type
=
"s3"
ServerAddress
=
"s3.amazonaws.com"
AccessKey
=
"<your AWS Access Key ID>"
SecretKey
=
"<your AWS Secret Access Key>"
BucketName
=
"<the bucket where your cache should be kept>"
BucketLocation
=
"us-east-1"
Shared
=
true
```
Here's some more info to get you started:
-
[
The `[runners.cache
]
` section](https://docs.gitlab.com/runner/configuration/advanced-configuration.html#the-runners-cache-section)
- [Deploying and using a cache server for GitLab Runner](https://docs.gitlab.com/runner/configuration/autoscale.html#distributed-runners-caching)
- [How cache works](../../ci/yaml/README.md#cache)
### `
[
runners.machine
]
`
This is the most important part of the configuration and it's the one that
tells GitLab Runner how and when to spawn new Docker Machine instances.
```toml
[runners.machine]
IdleCount = 1
IdleTime = 1800
MaxBuilds = 100
MachineDriver = "amazonec2"
MachineName = "gitlab-docker-machine-%s"
OffPeakPeriods = ["* * 0-7,19-23 * * mon-fri *", "* * * * * sat,sun *"]
OffPeakIdleCount = 0
OffPeakIdleTime = 1200
MachineOptions = [
"amazonec2-access-key=XXXX",
"amazonec2-secret-key=XXXX",
"amazonec2-region=us-east-1",
"amazonec2-vpc-id=vpc-xxxxx",
"amazonec2-subnet-id=subnet-xxxxx",
"amazonec2-use-private-address=true",
"amazonec2-tags=Name,gitlab-runner-autoscale",
"amazonec2-security-group=docker-machine-scaler",
"amazonec2-instance-type=m4.2xlarge",
"amazonec2-ssh-user=ubuntu",
"amazonec2-ssh-keypath=/etc/gitlab-runner/certs/gitlab-aws-autoscaler",
"amazonec2-zone=a",
"amazonec2-root-size=32",
]
```
TIP: **Tip:**
Under `
MachineOptions
` you can add anything that the [AWS Docker Machine driver
supports](https://docs.docker.com/machine/drivers/aws/#options).
