+# Instructions for building and deploying a new image
+
+
+In all the following replace `<HASH>` with latest commit hash.
+
+
+## Build and push new image
+
+```
+docker build -t us-east4-docker.pkg.dev/elementalcognition-app-source/docker-all/lyft/flinkk8soperator:<HASH> --progress=plain .
+```
+
+```
+docker push us-east4-docker.pkg.dev/elementalcognition-app-source/docker-all/lyft/flinkk8soperator:<HASH>
+```
+
+## Edit the deployment directly, for testing
+```
+kubectl edit deploy lyft-flink-flink-operator -n lyft-flink-operator
+```
+
+And change the previous hash to the new one (I changed two locations - one in the image name and one elsewhere).
+
+## Update the infrastructure repo
+
+Once changes are tested, to make them permanent, merge a PR in the infrastrucutre repo, for example:
+https://github.com/ElementalCognition/infrastructure/commit/875ed9c6f657300d2ca221ff11c610d63368e918
