### Build-in docker image

- build docker image `docker build -t monit .`

- start monit: `docker run --rm -it -p 2812:2812 -v $(pwd)/monitrc:/etc/monitrc monit`
> note: monitrc is a file! create before docker run.

### Build-in docker image arm64

- build docker image `docker buildx build --platform arm64 -t monit .`

- start monit: `docker run --rm -it -p 2812:2812 -v $(pwd)/monitrc:/etc/monitrc monit`
> note: monitrc is a file! create before docker run.

### Docker Hub image

- pull docker image from gitlab: `docker pull registry.gitlab.com/manalejandro/monit-docker/monit:latest`

- start monit: `docker run --rm -it -p 2812:2812 -v $(pwd)/monitrc:/etc/monitrc registry.gitlab.com/manalejandro/monit-docker/monit:latest`

- create a docker container:

```bash
docker create \
  --name=monit \
  -p 2812:2812 \
  -v $(pwd)/monitrc:/etc/monitrc \
  registry.gitlab.com/manalejandro/monit-docker/monit:latest
```

### Docker compose

- create a container using docker-compose: `docker-compose up --no-start`

- start monit: `docker-compose up`

### Troubleshooting

If when starting Monit returns the following message: `The control file '/etc/monitrc' permission 0755 is wrong, maximum 0700 allowed`, simply give the appropriate permissions to _monitrc_: `chmod 700 monitrc`.

If when starting Monit returns the following message: `input in flex scanner failed`, simply you need to create an empty file with name `monitrc` in your source folder will do.
