+***Attention:** For using Docker commands in Apple M1 environments!*

+# set env variable for your shell
+$ export DOCKER_DEFAULT_PLATFORM=linux/amd64

+
+## Analysing Docker Builds
+
+To analyze a Docker build, there is a wonderful tool called [dive](https://github.com/wagoodman/dive). Please sponsor if you're using it!
+
+The `dive build` command is exactly the right one to fulfill what we are looking for.
+We can use it just like the `docker build` command and get an analysis afterwards.
+
+So, in our main folder, we use it in the following way:
+
+```bash
+# in main folder
+$ dive build --target <layer-name> -t "ocelotsocialnetwork/<app-name>:local-<layer-name>" --build-arg BBUILD_DATE="<build-date>" --build-arg BBUILD_VERSION="<build-version>" --build-arg BBUILD_COMMIT="<build-commit>" <app-folder-name-or-dot>/
+```
+
+The build arguments are optional.
+
+For the specific applications, we use them as follows.
+
+### Backend
+
+#### Production For Backend
+
+```bash
+# in main folder
+$ dive build --target production -t "ocelotsocialnetwork/backend:local-production" backend/
+```
+
+#### Development For Backend
+
+```bash
+# in main folder
+$ dive build --target development -t "ocelotsocialnetwork/backend:local-development" backend/
+```
+
+### Webapp
+
+#### Production For Webapp
+
+```bash
+# in main folder
+$ dive build --target production -t "ocelotsocialnetwork/webapp:local-production" webapp/
+```
+
+#### Development For Webapp
+
+```bash
+# in main folder
+$ dive build --target development -t "ocelotsocialnetwork/webapp:local-development" webapp/
+```
