Jenkins requires a certificate to use the ssh publication and ssh commands. It can be configured under 'manage jenkins' - 'Configure System'- 'publish over ssh'. The question is: How does one create the certificates? I have two ubuntu servers, one running Jenkins, and one for running the app. Oct 25, 2017 We made an intentional decision to generate and use a Jenkins provided SSH key for Git repositories. The reasons are: Enhanced Security - it is not good security practice for users to store personal their SSH key in Jenkins. Typically these keys can be used to gain access to other systems, such as machines running production workloads. And the Jenkins credential with ssh auth key method have been created. Set up Slave Nodes Now we will setup the slave nodes server by installing java on those servers and create a new Jenkins user.

In this guide, I will walk you through the steps for setting up the Jenkins slaves. There are two ways of authentication for setting up the Jenkins slaves.

`dockerNode`: Docker Node (⚠️ Experimental)

Allocates a new Jenkins agent using a specified Docker image and runs tasks on it. Example:

image
- Type:String
connector (optional)
- attach
  - user (optional)
    User under that jenkins slave will be run. 'root' if not specified.
    - Type:String
- jnlp
  - jnlpLauncher
    - tunnel
      Type:String
    - vmargs
      If the agent JVM should be launched with additional VM arguments, such as '-Xmx256m', specify those here. List of all the options are available here.
      Type:String
  - entryPointArgumentsString (optional)
    - Type:String
  - jenkinsUrl (optional)
    If needed, the Jenkins URL can be overwritten with this property (e.g. to support other HTTP(S) endpoints due to reverse proxies or firewalling). By default the URL from the global Jenkins configuration is used.
    - Type:String
  - user (optional)
    User under that jenkins slave will be run. 'root' if not specified.
    - Type:String
- ssh
  - sshKeyStrategy
    Define how a SSH key pair is configured for ssh authentication in container.
    - $class: 'InjectSSHKey'
      user
      Injected SSH key will let agent start as root in container. If you want to use another user configure it's name here. Please note such a user must pre-exist in container image.
      Type:String
    - $class: 'ManuallyConfiguredSSHKey'
      credentialsId
      Type:String
      sshHostKeyVerificationStrategy
      Nested Choice of Objects
      $class: 'KnownHostsFileKeyVerificationStrategy'
      Checks the known_hosts file (~/.ssh/known_hosts) for the user Jenkins is executing under, to see if an entry exists that matches the current connection.
      This method does not make any updates to the Known Hosts file, instead using the file as a read-only source and expecting someone with suitable access to the appropriate user account on the Jenkins master to update the file as required, potentially using the ssh hostname command to initiate a connection and update the file appropriately.
      $class: 'ManuallyProvidedKeyVerificationStrategy'
      Checks the key provided by the remote host matches the key set by the user who configured this connection.
      key
      The SSH key expected for this connection. This key should be in the form `algorithm value` where algorithm is one of ssh-rsa or ssh-dss, and value is the Base 64 encoded content of the key.
      Type:String
      $class: 'ManuallyTrustedKeyVerificationStrategy'
      Checks the remote key matches the key currently marked as trusted for this host.
      Depending on configuration, the key will be automatically trusted for the first connection, or an authorised user will be asked to approve the key. An authorised user will be required to approve any new key that gets presented by the remote host.
      requireInitialManualTrust
      Require a user with Computer.CONFIGURE permission to authorise the key presented during the first connection to this host before the connection will be allowed to be established.
      If this option is not enabled then the key presented on first connection for this host will be automatically trusted and allowed for all subsequent connections without any manual intervention.
      Type:boolean
      $class: 'NonVerifyingKeyVerificationStrategy'
      Does not perform any verification of the SSH key presented by the remote host, allowing all connections regardless of the key they present.
  - javaPath (optional)
    - Type:String
  - jvmOptions (optional)
    - Type:String
  - launchTimeoutSeconds (optional)
    - Type:int
  - maxNumRetries (optional)
    The number of times that attempts to connect to the newly-spun Docker container will be retried before the operation is abandoned.
    Note: That this field applies first to checks that the SSH port is open for new TCP connections, and secondly to checks that the SSH service that owns the TCP port is accepting SSH connections.
    e.g. a value of 3 would mean that (up to) 4 attempts (1 initial attempt plus 3 retries) would be made to check the availability of the TCP port, followed by (up to) 4 attempts (1 initial attempt plus 3 retries) to check the availability of the SSH service itself.
    - Type:int
  - port (optional)
    - Type:int
  - prefixStartSlaveCmd (optional)
    - Type:String
  - retryWaitTime (optional)
    Number of seconds to wait between attempts to connect to the newly-started Docker container.
    - Type:int
  - suffixStartSlaveCmd (optional)
    - Type:String
credentialsId (optional)
- Type:String
dockerHost (optional)
- Type:String
remoteFs (optional)
Use a specific root directory for the Jenkins agent. This includes a workspace subdirectory as well as various control files. If not specified, uses the WORKDIR from the image.
- Type:String

`step([$class: 'DockerBuilderPublisher'])`: Build / Publish Docker Image

Build step that sends a Dockerfile for building to docker host that used for this build run.

dockerFileDirectory
- Type:String
fromRegistry

  URL to the Docker registry you are using. May be left blank to use the public DockerHub registry (currently https://index.docker.io/v1/).
  - Type:String
- credentialsId
  - Type:String
cloud
Cloud to do the build on - or, if empty, use the cloud that the build was performed on.
- Type:String
tagsString
Repository name (and optionally a tag) to be applied to the resulting image in case of success.
Multiple entries are permitted if separated by newlines.
Environment variable substitution is performed on the strings so you can use e.g. ${BUILD_NUMBER} as part of each entry.
Each entry must be of the form IMAGE[:TAG] as per the docker tag command.
- Type:String
pushOnSuccess
If enabled (and the docker image builds successfully), the resulting docker image will be pushed to the registry (or registries) specified within the 'Image' field.
- Type:boolean
pushCredentialsId
- Type:String
cleanImages
- Type:boolean
cleanupWithJenkinsJobDelete
- Type:boolean
noCache (optional)
If set, builds the image with --no-cache which disables caching of layers. See the docker build command for more information.
- Type:boolean
pull (optional)
If set, builds the image with --pull to pull the latest version of the base image, instead of using the local one. See the docker build command for more information.
- Type:boolean
