How to enable / setup Dependency Caches for apt-get on BitBucket Pipelines

Question

I am using the following code in my bitbucket-pipelines.yml files to remotely deply code to a staging server.

image: php:7.1.1  pipelines:   default:     - step:         script:           # install ssh           - apt-get update && apt-get install -y openssh-client           # get the latest code           - ssh [email protected] -F ~/.ssh/config "cd /path/to/code && git pull"           # update composer           - ssh [email protected] -F ~/.ssh/config "cd /path/to/code && composer update --no-scripts"           # optimise files           - ssh [email protected] -F ~/.ssh/config "cd /path/to/code && php artisan optimize" 

This all works, except that each time the pipeline is run, the ssh client is downloaded and installed everything (adding ~30 seconds to the build time). Is there way I can cache this step?

And how can I go about caching the apt-get step?

For example, would something like this work (or what changes are needed to make the following work):

pipelines:   default:     - step:         caches:           - aptget         script:           - apt-get update && apt-get install -y openssh-client  definitions:   caches:     aptget: which ssh

This is a typical scenario where you should use your own Docker image instead of one of the ones provided by Atlassian. (Or search for a Docker image which provides exactly this.)

In your simple case, this Dockerfile should be enough:

FROM php:7.1.1  RUN apt-get update && \     apt-get install -y openssh-client 

Then, create a DockerHub account, publish the image and reference it in bitbucket-pipelines.yml.
