# Installazione

## Homebrew (Mac OS X / Linux e WSL)

Puoi usare Homebrew su [Mac OS X](https://brew.sh/) o [Linux e WSL (Windows Subsystem for Linux)](https://docs.brew.sh/Homebrew-on-Linux).```bash
$ brew install goodwithtech/r/dockle

## Debian/Ubuntu```bash
VERSION=$(
 curl --silent "https://api.github.com/repos/goodwithtech/dockle/releases/latest" | \
 grep '"tag_name":' | \
 sed -E 's/.*"v([^"]+)".*/\1/' \
) && curl -L -o dockle.deb https://github.com/goodwithtech/dockle/releases/download/v${VERSION}/dockle_${VERSION}_Linux-64bit.deb
$ sudo dpkg -i dockle.deb && rm dockle.deb

## Windows```bash
VERSION=$(
 curl --silent "https://api.github.com/repos/goodwithtech/dockle/releases/latest" | \
 grep '"tag_name":' | \
 sed -E 's/.*"v([^"]+)".*/\1/' \
) && curl -L -o dockle.zip https://github.com/goodwithtech/dockle/releases/download/v${VERSION}/dockle_${VERSION}_Windows-64bit.zip
$ unzip dockle.zip && rm dockle.zip
$ ./dockle.exe [IMAGE_NAME]

## Binary

Puoi ottenere l'ultima versione binaria dalla [pagina delle release](https://github.com/goodwithtech/dockle/releases/latest).

Scarica il file di archivio per il tuo sistema operativo/architettura. Estrai l'archivio e metti il binario da qualche parte nel tuo `$PATH` (su sistemi UNIX, `/usr/local/bin` o simili).

- NOTA: assicurati che i bit di esecuzione siano attivi. (`chmod +x dockle`)

## asdf

Puoi installare dockle con il [gestore di versioni asdf](https://asdf-vm.com/) tramite questo [plugin](https://github.com/mathew-fleisch/asdf-dockle), che automatizza il processo di installazione (e passaggio) tra varie versioni dei binari delle release di GitHub. Con asdf già installato, esegui questi comandi per installare dockle:```bash
# Add dockle plugin
asdf plugin add dockle

# Show all installable versions
asdf list-all dockle

# Install specific version
asdf install dockle latest

# Set a version globally (on your ~/.tool-versions file)
asdf global dockle latest

# Now dockle commands are available
dockle --version

## Dal sorgente```bash
$ GO111MODULE=off go get github.com/goodwithtech/dockle/cmd/dockle
$ cd $GOPATH/src/github.com/goodwithtech/dockle && GO111MODULE=on go build -o $GOPATH/bin/dockle cmd/dockle/main.go

You only need `-v /var/run/docker.sock:/var/run/docker.sock` when you'd like to scan the image on your host machine.

# Quick Start

## Basic

Basta specificare un nome di immagine (e un tag).```bash
$ dockle [YOUR_IMAGE_NAME]

### Ottieni o Salva i risultati come JSON```bash
$ dockle -f json goodwithtech/test-image:v1
$ dockle -f json -o results.json goodwithtech/test-image:v1

          }
        }
      ]
    }
  ]
}

### Specify exit level

Per impostazione predefinita, `--exit-code` viene eseguito quando ci sono avvisi di livello `WARN` o `FATAL`. Usa l'opzione `--exit-level, -l` per modificare il livello di avviso. Puoi impostare `info`, `warn` o `fatal`.```bash
$ dockle --exit-code 1 --exit-level info [IMAGE_NAME]
$ dockle --exit-code 1 --exit-level fatal [IMAGE_NAME]

Oppure, usa `DOCKLE_IGNORES`:```
export DOCKLE_IGNORES=CIS-DI-0001,DKL-DI-0006
dockle [IMAGE_NAME]

### Accetta sospette `variabili d'ambiente` / `file` / `estensioni di file````bash
# --accept-key value, --ak value             You can add acceptable keywords.
dockle -ak GPG_KEY -ak KEYCLOAK_VERSION [IMAGE_NAME]
or DOCKLE_ACCEPT_KEYS=GPG_KEY,KEYCLOAK_VERSION dockle [IMAGE_NAME]

# --accept-file value, --af value            You can add acceptable file names.
dockle -af id_rsa -af id_dsa [IMAGE_NAME]
or DOCKLE_ACCEPT_FILES=id_rsa,id_dsa dockle [IMAGE_NAME]

# --accept-file-extension value, --ae value  You can add acceptable file extensions.
dockle -ae pem -ae log [IMAGE_NAME]
or DOCKLE_ACCEPT_FILE_EXTENSIONS=pem,log dockle [IMAGE_NAME]

## Integrazione Continua (CI)

Puoi scansionare l'immagine costruita con `Dockle` in Travis CI/CircleCI.

In questi esempi, il test fallirà se vengono trovati avvisi.

Tuttavia, puoi ignorare i checkpoint specificati utilizzando il file `.dockleignore`.

Oppure, se vuoi solo visualizzare i risultati e non far fallire il test per questo, imposta `--exit-code` su `0` nel comando `dockle`.
