Building PivotalMySQLWeb using Cloud Native Buildpacks (CNB)
http://theblasfrompas.blogspot.com/2019/06/building-pivotalmysqlweb-using-cloud.html
In the steps below I will show how to use a local docker registry on your laptop or desktop to enable faster builds of your OCI compliant images using CNB's. Here is how using the same application.
Pre Steps:
1. Ensure you have Docker CE installed if not use this link
https://hub.docker.com/search/?type=edition&offering=community
Steps:
1. Start by running a local registry on your own laptop. The guide shows how to get a container running which will be our local registry and then how you verify it's running.
https://docs.docker.com/registry/
$ docker run -d -p 5000:5000 --restart=always --name registry registry:2
Verify it's running:
$ netstat -an | grep 5000
tcp6 0 0 ::1.5000 *.* LISTEN
tcp4 0 0 *.5000 *.* LISTEN
2. Then pull the CNB images versions of the "official" build and run images from the GCR as follows. Those images exist here
https://console.cloud.google.com/gcr/images/cncf-buildpacks-ci/GLOBAL/packs/run?gcrImageListsize=30
Here I am using the latest build/run images which at the time of this post was "run:0.2.0-build.12"
papicella@papicella:~$ docker pull gcr.io:443/cncf-buildpacks-ci/packs/run:0.2.0-build.12

3. Now lets use our local registry and build/run images which will be much faster for local development

Here is how to view your local registry using HTTPie showing our locally built "pivotal-mysql-web" OCI image we created above
