问题
I have a maven spring-boot project deployed on appengine that I am building and deploying using Google Cloud Build using the following builder image: https://github.com/strudeau/mvn-gcloud-builder
When performing a build, most of the time is spent downloading the plugins and dependencies from maven. I would like to be able to mount a persistent volume to this Docker image so as to be able to keep a persistent .M2 directory where my plugins and dependencies would be stored to avoid having them downloaded each time I do a build.
Google Cloud Filestore would probably be ideal if it weren't for the fact that you have to provision 1TB of data or more which becomes ridiculously expensive for a small non-production profit project.
- Is there a way to mount a bucket as a filesystem on the docker image?
- Can I mount a
Google Persistent Disk?
回答1:
You can't mount a bucket into the build, but you can copy your .M2 directory out to a bucket at the end of a build, then restore it at the beginning of a subsequent build.
I've lifted the example directly from the documentation, in case it disappears.
steps:
- name: gcr.io/cloud-builders/gsutil
args: ['cp', 'gs://mybucket/results.zip', 'previous_results.zip']
# operations that use previous_results.zip and produce new_results.zip
- name: gcr.io/cloud-builders/gsutil
args: ['cp', 'new_results.zip', 'gs://mybucket/results.zip']
Watch out when mixing this strategy with concurrent builds.
