DovnarAlexander/jenkins

Ansible Galaxy DovnarAlexander/jenkins

This role helps you to install any version of Jenkins (LTS and Not). It manages:

• Jenkins users;
• Credentials (SSH including key generation, Secret Text and Username-Password);
• Installs plugins;
• Jenkins Slaves (JNLP and SSH);
• Some Jenkins main configuration (the main Hostname and Email).
• You can manage as much as possible when you do not have direct SSH connection to Jenkins with "Remote_Jenkins" tag.
