Pros
Pro Docker integration
Shippable is built using Docker, a popular open source Linux container. It was originally built using it's own container but when that started to become too complex, they switched to using Docker. Since the beginning Shippable was different from other CI tools because while Shippable uses a container (Docker), traditionally CI tools have used virtual machines to manage their workloads.
Pro Builds are faster
The fact that Shippable runs inside of Docker means that it keeps a persistent state and every build will not have to revert to initial state where it needs to install every dependency from the ground up. Classic CI tools that run on virtual machines need to reset their environment every time and every time install the gems, packages and services needed.
Cons
Con Docker security measures may be a hindrance
Shippable runs inside Docker containers. Docker has some specific security measures which may or may not become a hindrance in using Shippable. It may be harder for users who are not very comfortable with a Linux container environment and that can create some security problems. Even for more advanced users, it's still something more that they have to address while using Shippable.
Con No Direct Deploy to S3
Currently, Shippable does not allow for build artifacts to be natively deployed to S3. This can be gotten around, however it is a rather large hole when compared to Travis.
In order to deploy to S3 you have to add a couple of lines to the yml file. For example:
env:
global:
#secure variable contains values for AWS_ACCESS_KEY_ID and AWS_SECRET_ACCESS_KEY
- secure: HKwYujx/qmsyQQdHvR2myu8HLUDtcLeDyYV149YJuxIV4J7Hk3SxeY8X3D6aTlR8mvMnd/ZFY+tGNUh4G0xtLLjjZcPsBgvFlB
build:
on_success:
- aws s3 sync $SHIPPABLE_BUILD_DIR "s3://bucket_name" --region "us-east-1"
