# Docker More Closely
## Apple M1 Platform
***Attention:** For using Docker commands in Apple M1 environments!*
### Environment Variable For Apple M1 Platform
To set the Docker platform environment variable in your terminal tab, run:
```bash
# set env variable for your shell
$ export DOCKER_DEFAULT_PLATFORM=linux/amd64
```
### Docker Compose Override File For Apple M1 Platform
For Docker compose `up` or `build` commands, you can use our Apple M1 override file that specifies the M1 platform:
```bash
# in main folder
# for development
$ docker compose -f docker-compose.yml -f docker-compose.override.yml -f docker-compose.apple-m1.override.yml up
# only once: init admin user and create indexes and constraints in Neo4j database
$ docker compose exec backend yarn prod:migrate init
# clean db
$ docker compose exec backend yarn db:reset
# seed db
$ docker compose exec backend yarn db:seed
# for production
$ docker compose -f docker-compose.yml -f docker-compose.apple-m1.override.yml up
# only once: init admin user and create indexes and constraints in Neo4j database
$ docker compose exec backend /bin/sh -c "yarn prod:migrate init"
```
## 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/
```
