For a parameterized assembly with an image tag selection, you will need the Active Choices plugin
Go to “Manage Jenkins”
Section “Manage Plugins”
Go to the “Available” tab and select “Active Choices” in the search.
Install it.
Create a “New Item” – “Pipeline“, indicate that it will be a parameterized assembly, and add the parameter “Active Choices Parameter”
We indicate that this is “Groovy Script” and paste the following into it:
import com.cloudbees.plugins.credentials.Credentials;
import com.cloudbees.plugins.credentials.CredentialsNameProvider;
import com.cloudbees.plugins.credentials.common.StandardCredentials;
import com.cloudbees.jenkins.plugins.sshcredentials.SSHUserPrivateKey;
import com.jcraft.jsch.JSch;
import com.jcraft.jsch.Session;
import com.jcraft.jsch.ChannelExec;
import jenkins.model.*
sshCredentialsId = 'instance_ssh_key'
sshUser = 'artem'
sshInstance = '192.168.1.100'
def sshCreds = com.cloudbees.plugins.credentials.CredentialsProvider.lookupCredentials(SSHUserPrivateKey.class, Jenkins.instance, null, null ).find({it.id == sshCredentialsId});
String ssh_key_data = sshCreds.getPrivateKeys()
JSch jsch = new JSch();
jsch.addIdentity("id_rsa", ssh_key_data.getBytes(), null, null);
Session session = jsch.getSession(sshUser, sshInstance, 22);
Properties prop = new Properties();
prop.put("StrictHostKeyChecking", "no");
session.setConfig(prop);
session.connect();
ChannelExec channelssh = (ChannelExec)session.openChannel("exec");
channelssh.setCommand("cat /home/artem/secret_list");
channelssh.connect();
def result = []
InputStream is=channelssh.getInputStream();
is.eachLine {
result.add(it)
}
channelssh.disconnect();
return result
Where is the value of the variables, “sshCredentialsId” – Jenkins Credentials ID with type: “SSH Username with private key”;
“sshUser” – username for SSH connection;
“sshInstance” – IP address or domain name of the remote instance;
“cat /home/artem/secret_list” – the command whose result we want to return
