DockerBuild - Vitess

We created the lite image as a stripped down version of our old image base such that Kubernetes pods can start faster. The lite image is updated automatically after every push to the GitHub main branch.

For more information on the different images we provide, please read the docker/README.md file.

If your goal is run the latest Vitess code, the simplest solution is to use the lite.

Another alternative is to customize our Docker images and build them yourselves. This is described below and involves building the base image first. Then you can run our build script for the lite image which extracts the Vitess binaries from the built base image.

Install Docker on your workstation.

Our scripts also assume you can run the docker command without sudo, which you can do by setting up a docker group.
Create an account on Docker Hub and then docker login to it.
Go to your src/vitess.io/vitess directory.
Usually, you won't need to build your own bootstrap image unless you edit bootstrap.sh or vendor.json, for example to add new dependencies. If you do need it then build the bootstrap image, otherwise pull the image using one of the following command.
sh
```
vitess$ docker pull vitess/bootstrap:latest
```
Note: If you have already downloaded the vitess/bootstrap:<flavor> image on your machine before then it could be old, which may cause build failures. So it would be a good idea to always execute this step.
Build the vitess/lite[:<flavor>] image. This will run a script that extracts from vitess/bootstrap only the files needed to run Vitess.
sh
```
vitess$ make docker_lite
```
Re-tag the image under your personal repository, then upload it.
sh
```
vitess$ docker tag -f vitess/lite yourname/vitess
vitess$ docker push yourname/vitess
```
Note: If you chose a non-default flavor above, then change vitess/lite in the above command to vitess/lite:<flavor>.
Launch Vitess on Kubernetes as usual.
