## Image Update

After making changes to files in the directory, you must run the following
commands to update the image Kokoro uses:

```shell
gcloud config set project gvisor-kokoro-testing
third_party/gvisor/kokoro/ubuntu1604/build.sh
third_party/gvisor/kokoro/ubuntu1804/build.sh
```

Note: the command above will change your default project for `gcloud`. Run
`gcloud config set project` again to revert back to your default project.

Note: Files in `third_party/gvisor/kokoro/ubuntu1804/` as symlinks to
`ubuntu1604`, therefore both images must be updated.

After the script finishes, the last few lines of the output will container the
image name. If the output was lost, you can run `build.sh` again to print the
image name.

```

```

To setup Kokoro to use the new image, copy the image names to their
corresponding file below:

*   //devtools/kokoro/config/gcp/gvisor/ubuntu1604.gcl
*   //devtools/kokoro/config/gcp/gvisor/ubuntu1804.gcl
