How can I find initial password for jenkins?

Question

I already searched the related questions like here;

How do I get initial admin password for jenkins on Mac?

and here;

How to recover Jenkins password

However, I cannot find a solution for my problem.

I am following the instructions to install jenkins on this link;

https://jenkins.io/doc/book/installing/

and I have run the following commands to install and tried to make it run on my local machine (mac os);

docker run \
  -u root \
  --rm \
  -d \
  -p 8080:8080 \
  -p 50000:50000 \
  -v jenkins-data:/var/jenkins_home \
  -v /var/run/docker.sock:/var/run/docker.sock \
  jenkinsci/blueocean

It installs it properly but when I get to the login screen it asks for the initial admin password. Because the installation runs in (-d mode) backend, I cannot see the initial password after the installation completes. When I remove -d for the installation, then the installation does not work.

I also checked the shared folder (User/Shared/Jenkins/Home) directory and there was no secrets folder in it. So I created one manually and followed the instructions (in the answers) on this link again;

How do I get initial admin password for jenkins on Mac?

Afterwards, I removed the related docker process and restarted all the installation process from the beginning but I got the same result.

In this case, how can I find this initial admin password or how can I generate it again?

BTW: I am also checking the logs (where in /var/log/jenkins) but it seems that it stopped writing there after my first install attempt and I also couldn't find the initial password there).

This worked for me but looking at the logs did not. – OSE Apr 19 '19 at 19:33
This should be actually the accepted response. I mean: there's no use on reconstructing the whole container or the logging part referencing out the password could well have been lost/passed. – Hugo Tavares Jul 25 '19 at 15:42

I tried looking into the container's filesystem, but there's no secrets folder in it. But I found the solution in the jenkins documentation here

Docker outputs the initial secret to the console

To view the console use the command

docker logs <container id of jenkins>

output is somemthing like this:

If you are using Mac and Docker installation for Jenkins follow bellow steps to get initial administer password to start authentication in Jenkins Console. Type below command in Terminal.

(Note: This is working, if you have follow default steps in Jenkins documentation to install Jenkins in Docker environment)

Find the running containers

: docker ps

Copy the running containerID

: docker exec -it <containerID> bash

: cd /var/jenkins_home/secrets

: cat initialAdminPassword

Use secret password showing in terminal and used as initial password for Jenkins Console.

If you have installed Jenkins via docker, then the following command can give you the initial admin password. Assuming your container name/docker image name is jenkins

docker exec `docker ps | grep jenkins | awk '{ print $1}' ` cat /var/jenkins_home/secrets/initialAdminPassword

Worked great for me. I had to replace instances of `docker` with `sudo docker`. – jxmorris12 Jun 17 '20 at 19:49

Use `sudo usermod -aG docker $USER` if want to avoid typing sudo all the time – akshaykrjain Jun 18 '20 at 05:26

For me username was: admin and you can find password by:

docker exec jenkins cat /var/jenkins_home/secrets/initialAdminPassword

my container name is jenkins

Can you install docker-compose and docker toolbox on your Mac? https://docs.docker.com/compose/install/ Try to execute this docker-compose.yml file:

version: '3.1'
services:

  blue-ocean:
    image: jenkinsci/blueocean:latest
    container_name: blue-ocean
    restart: always
    environment:
      TZ: America/Mexico_City
    ports:
      - 8080:8080
      - 50000:50000
    tty: true
    volumes:
      - ./jenkins-data:/var/jenkins_home
      - ./sock:/var/run/docker.sock

Only you need to create a folder with a docker-compose.yml file inside and execute the docker-compose up -d command in terminal, then the folders jenkins-data and sock will be created and inside of jenkins-data appear the directory ./jenkins-data/secrets/initialAdminPassword, open this file and copy the content and paste on the input of web view that requires it.

Hi, I don't have 'secrets' folder in 'jenkins-data' folder. So, I cannot find the initialAdminPassword file. Why does that happen? – Jun 24 '18 at 15:19

After awhile, the 'secrets' folder was created. Now, I found it and could pass the password page :) Thank you very much! – Jun 24 '18 at 15:23
I believe this answer is not good. Why? Although it works, it is not answering with an actionable solution for the problem so it shouldn't be taken as acceptable answer. Also @user2147431 should be made aware that the folder ".../secrets/..." is not on the host OS (macOS, Linux, whatever... is the same on every Docker deployment) but on the guest/container's once it's bootstrapped. – Hugo Tavares Jul 25 '19 at 15:49
