* - contextDir - String - Répertoire servant de "contexte" pour la construction de l'image, par défault "./"
* - imageName - String - Nom de l'image à construire, par défaut ""
* - imageTag - String - Tag apposé sur l'image après construction, par défaut résultat de la commande `git describe --always`
* - gitCredentialsId - String - Identifiant des "credentials" Jenkins utilisés pour cloner le dépôt Git, par défaut "forge-jenkins"
* - dockerRepository - String - Nom d'hôte du registre Docker sur lequel publier l'image, par défaut "reg.cadoles.com"
* - dockerRepositoryCredentialsId - String - Identifiant des "credentials" Jenkins utilisés pour déployer l'image sur le registre Docker, par défault "reg.cadoles.com-jenkins"
* - dryRun - Boolean - Désactiver/activer la publication de l'image sur le registre Docker, par défaut "true"
