I'm trying to create a buildpack with libwebp, and I'm trying to follow this tutorial, which starts with the following commands:
heroku create buildpack-stager
heroku run bash --app buildpack-stager
curl -O https://mupdf.googlecode.com/files/mupdf-1.3-source.tar.gz
tar -xvzf mupdf-1.3-source.tar.gz
...
Should these initial commands be run in the terminal of my application on heroku?
heroku create should be run on your local machine. This creates a new app on Heroku, so if you already have an app to work with it may not be necessary.
heroku run bash should also be run on your local machine. This spins up a one-off dyno for your app and runs the command bash on it.
From there, it looks like they want you to continue with curl, tar, etc. in the same shell as the previous step. The effect will be that these commands are run on the one-off dyno you're using, but you don't need to change terminals or anything.
You might find the Heroku CLI commands documentation page helpful.
All these commands you should run on your local terminal (bash, etc.)
I have a perfectly fine Swift-Docker-Kitura project on a Mac ...
You work on the code using Xcode, and then in terminal you docker build. It builds. You docker run and you can even see the web page locally on localhost. You can then docker push and it goes to the main AWS cloud and is hosted.
That's all great.
But what if I want to use Swift-Docker-Kitura "not on a Mac"?
Can you "build" and "push" such a swift project - on some sort of shell on AWS (or a similar service)?
There are multiple options to build and run Kitura web applications, though not all of the options are officially supported.
Run it from an Xcode project on Mac, build in Xcode.
Run it in the command line on Mac, build using swift build.
Run it in the command line on Ubuntu, build using swift build.
Run it on a cloud that supports Cloud Foundry buildpacks. See https://github.com/IBM-Swift/swift-buildpack. For example, on IBM Bluemix, see https://console.bluemix.net/catalog/starters/runtime-for-swift.
Run it in an Ubuntu docker, see http://www.kitura.io/en/starter/leveragedocker.html, on any platform that supports docker.
Create a docker image with the Kitura application code (see https://github.com/IBM-Swift/swift-ubuntu-docker#using-ibmcomswift-ubuntu-runtime) and push it to any cloud that supports executing docker images. For example, IBM Bluemix Kubernetes Cluster https://console.bluemix.net/containers-kubernetes/catalogCluster.
You can even embed it in an iOS application, see https://developer.ibm.com/swift/2017/03/13/kitura-ios/.
And you can run it on a mainframe, see https://developer.ibm.com/swift/2017/10/05/swift-zos-swift-4-0-beta-update/.
From iPhone to mainframe, on Mac, Ubuntu, Docker and various cloud providers, these are the options to run Kitura.
Disclaimer: I work in IBM. As of the day of this edit (December 28-th 2017), to my best knowledge, Kitura is supported by IBM only in the environments described here https://developer.ibm.com/swift/2017/10/30/commercial-support/.
Your options are limited. First of all Swift is only certified at this moment on Ubuntu. So the host you want to develop on either must run Ubuntu or alternatively must run Docker under which you can run Ubuntu.
In theory you can also compile swift on your target host. I did this for an older version of Swift once for Debain (Jessie) and although I managed to get it compiled it was certainly not stable. Things may have improved since then, I haven't checked that.
So the easiest way is to rely on Docker. This also allows you to still develop on your mac by editing in Xcode and then on the command line you have the options to compile it manually.
I use the following bash function to open my Linux environment:
SwiftDocker2 ()
{
name=`perl -e 'open IN, "</usr/share/dict/words";rand($.) \
< 1 && ($n=$_) while <IN>;print $n'`;
docker run -i -t --name=${name} -h ${name} --log-driver=json-file \
-w /project -v $(pwd):/project -p 9000:9000 ibmcom/swift-ubuntu /bin/bash;
echo "Created image ${name}";
echo "Stopping image";
docker stop ${name};
echo "Removing image";
docker rm ${name}
}
In the above example I open port 9000 which may not be required by your application.
The last point I would like to make is the use of the build directory. I use a Makefile to do the build and in the Makefile I have the following section:
BUILD_LINUX = "./.build-linux"
BUILD_MACOS = "./.build-macos"
UNAME = $(shell uname)
ifeq (${UNAME}, Darwin)
BUILD_PATH = ${BUILD_MACOS}
else
BUILD_PATH = ${BUILD_LINUX}
endif
xcode:
#swift package --build-path ${BUILD_PATH} -Xlinker -L/usr/local/lib generate-xcodeproj
build:
rm -f Package.pins
swift build --build-path ${BUILD_PATH} -Xlinker "-L/usr/local/lib"
By using this construction the MacOS environment will use the directory .build-macos for the build and Linux will use the file .build-Linux. The file Package.pins is removed during build to ensure that some memory about versions to use is not transferred between the two environments.
I am installing Jenkins 2 on windows,after installing,a page is opened,URL is:
http://localhost:8080/login?from=%2F
content of the page is like this:
Question:
How to "Unlock Jenkins"?
PS:I have looked for the answer in documentation and google.
Starting from version 2.0 of Jenkins you may use
-Djenkins.install.runSetupWizard=false
to prevent this screen.
Accroding to documentation
jenkins.install.runSetupWizard - Set to false to skip install wizard. Note that this leaves Jenkins unsecured by default.
Development-mode only: Set to true to not skip showing the setup wizard during Jenkins development.
More details about Jenkins properties can be found on this Jenkins Wiki page.
Check https://wiki.jenkins-ci.org/display/JENKINS/Logging to see where Jenkins is logging its files.
e.g. for Linux, use the command: less /var/log/jenkins/jenkins.log
And scroll down to the part: "Jenkins initial setup is required. An admin user has been created ... to proceed to installation:
[randompasswordhere] <--- Copy and paste
Linux
By default logs should be made available in /var/log/jenkins/jenkins.log, unless customized in /etc/default/jenkins (for *.deb) or via /etc/sysconfig/jenkins (for */rpm)
Windows
By default logs should be at %JENKINS_HOME%/jenkins.out and %JENKINS_HOME%/jenkins.err, unless customized in %JENKINS_HOME%/jenkins.xml
Mac OS X
Log files should be at /var/log/jenkins/jenkins.log, unless customized in org.jenkins-ci.plist
open file: e:\Program Files (x86)\Jenkins\secrets\initialAdminPassword
copy content file: 47c5d4f760014e54a6bffc27bd95c077
paste in input: http://localhost:8080/login?from=%2F
DONE
Some of the above instructions seem to have gone out of date. As of the released version 2.0, creating the following file will cause Jenkins to skip the unlock screen:
${JENKINS_HOME}/jenkins.install.InstallUtil.lastExecVersion
This file must contain the string 2.0 without any line terminators. I'm not sure if this is required but Jenkins also sets the owner/group to be the same as the Jenkins server, so that's probably a good thing to mimic as well.
I did not need to create the upgraded or .last_exec_version files.
I assume you were running jenkins.war manually with java -jar jenkins.war, then all logging information by default is output to standard out, just type the token to unlock jenkins2.0.
If you were not running jenkins with java -jar jenkins.war, then you can always follow this Official Document to find the correct log location.
Open your terminal and type code below to find all the containers.
docker container list -a
You will find jenkinsci/blueocean and/or docker:dind if not than
docker container run --name jenkins-docker --rm --detach ^
--privileged --network jenkins --network-alias docker ^
--env DOCKER_TLS_CERTDIR=/certs ^
--volume jenkins-docker-certs:/certs/client ^
--volume jenkins-data:/var/jenkins_home ^
--volume "%HOMEDRIVE%%HOMEPATH%":/home ^
docker:dind
and
docker container run --name jenkins-blueocean --rm --detach ^
--network jenkins --env DOCKER_HOST=tcp://docker:2376 ^
--env DOCKER_CERT_PATH=/certs/client --env DOCKER_TLS_VERIFY=1 ^
--volume jenkins-data:/var/jenkins_home ^
--volume jenkins-docker-certs:/certs/client:ro ^
--volume "%HOMEDRIVE%%HOMEPATH%":/home ^
--publish 8080:8080 --publish 50000:50000 jenkinsci/blueocean
run command
docker run jenkinsci/blueocean
or
docker run docker:dind
Copy and Paste the secret key.
One method to prevent the installation wizard is to do the following in $JENKINS_HOME:
Create an empty file named .last_exec_version
Create a file named upgraded
If left empty, a banner will prompt you to "upgrade" to 2.0 (which just means install a bunch of new plugins like Pipeline)
If the contents of that file is 2.0, you'll receive no banner and it will act like an regular old Jenkins install
Remember, this wizard is in place to prevent unauthorized access to Jenkins during setup. However, bypassing this wizard can be useful if, for example, you want to deploy automated installations of Jenkins with something like Ansible/Puppet/etc.
This was tested against Jenkins 2.0-beta-1 – so these instructions may not work in future beta or stable releases.
In the mac use:
sudo more /Users/Shared/Jenkins/Home/secrets/initialAdminPassword
I have seen a lot of response to the question, most of them were actually solution to it but they solve the problem when jenkins is actually run as a standalone CI without Application container using the command:
java -jar jenkins.war
But when running on Tomcat as it is the case in this scenario, Jenkins logs are displayed on the catalina logs since the software is running on a container.
So you need to go to the logs folder:
C:\Program Files\tomcat_folder\Tomcat 8.5\logs\catalina.log
in my own case. Just scroll almost to the middle to look for a generated password which is essentially a token and copy and paste it to unlock jenkins.
I hope this fix your problem.
Step 1: Open the terminal on your mac
Step 2: Concatenate or Paste
sudo cat **/Users/Shared/Jenkins/Home/secrets/initialAdminPassword**
Step 3: It will ask for password, type your mac password and enter
Step 4: A key would be generated.
Step 5: Copy and paste the security token in Jenkins
Step 6: Click continue
I found the token in the following file in the installation dir:
<jenkins install dir>\users\admin\config.xml
and the element
<jenkins.install.SetupWizard_-AuthenticationKey>
<key> THE KEY </key>
</jenkins.install.SetupWizard_-AuthenticationKey>
You might see it in the catalina.out. I installed Jenkins war in tomcat and I can see this in the catalina.out
The below method does not work anymore on 2.42.2
Create an empty file named .last_exec_version
Create a file named upgraded
If left empty, a banner will prompt you to "upgrade" to 2.0 (which just means install a bunch of new plugins like Pipeline)
If the contents of that file is 2.0, you'll receive no banner and it will act like an regular old Jenkins install
mostly jenkins will show you the path for initialAdminPassword if you dont find it there, then you have to check jenkins logs
in log you will see
05-May-2017 01:01:41.854 INFO [Jenkins initialization thread] jenkins.install.SetupWizard.init
Jenkins initial setup is required. An admin user has been created and a password generated.
Please use the following password to proceed to installation:
7c249e4ed93c4596972f57e55f7ff32e
This may also be found at: /opt/tomcat/.jenkins/secrets/initialAdminPassword
Use a lil shortcut to get to the folder:
cmd + shift + g
then insert /Users/Shared/Jenkins
there u can see the secrets folder - probably shows that it's locked.
to unlock it: right click on the folder and click info + click on the lock at the bottom. now u can change the rights shown at the bottom of the window
hope that helped :)
Greetings, Stefanie ^__^
If unable to find Jenkins password in the location C:\Windows\System32\config\systemprofile\.jenkins\secrets\initialAdminPassword
by installing Jenkins generic war on Tomcat server, try below
Solution:
Set environmental variable JENKINS_HOME to your jenkins path say
JENKINS_HOME ="C:/users/username/apachetomcat/webapps/jenkins"
Place Jenkins.war in the webapp folder of Tomcat and start Tomcat,
initial admin password gets generated in the path
C:\Program Files (x86)\Apache Software Foundation\Tomcat 9.0\webapps\jenkins\secrets\initialAdminPassword
Yet another way to bypass the unlock screen is to copy the UpgradeWizard state to the InstallUtil last execution version, add an install.runSetupWizard file with the contents 'false', and update the config.xml installStateName from NEW to RUNNING.
docker exec -it jenkins bash
sed -i s/NEW/RUNNING/ /var/jenkins_home/config.xml
echo 'false' > /var/jenkins_home/jenkins.install.runSetupWizard
cp /var/jenkins_home/jenkins.install.UpgradeWizard.state /var/jenkins_home/jenkins.install.InstallUtil.lastExecVersion
exit
docker restart jenkins
For reference, this is the command I use to run jenkins:
docker run --rm --name jenkins --network host -u root -d -v jenkins:/var/jenkins_home -v /var/run/docker.sock:/var/run/docker.sock jenkinsci/blueocean:1.16.0
You will also want to update the config with the Root URL:
echo "<?xml version='1.1' encoding='UTF-8'?><jenkins.model.JenkinsLocationConfiguration><jenkinsUrl>http://<IP>:8080/</jenkinsUrl></jenkins.model.JenkinsLocationConfiguration>" > jenkins.model.JenkinsLocationConfiguration.xml
exit
docker restart jenkins
In case, if you installed/upgraded new versions of jenkins and unable to find admin credentials on server then, ...
if you are using old version of jenkins and on the top of it you are trying to reinstall/upgrade new version of jenkins then,
the files under "JENKINS_HOME", namely -
${JENKINS_HOME}/jenkins.install.InstallUtil.lastExecVersion
${JENKINS_HOME}/jenkins.install.UpgradeWizard.state
will cause jenkins to skip the unlock (or admin credentials screen) and webpage directly ask you for username and password. even on server you will not able to find "${JENKINS_HOME}/secrets/initialAdminPassword".
In such case, don't get panic. just try to use old admin user creds in newly installed/upgraded jenkins server.
In simple language, if you have admin creds as admin/admin in old version of jenkins server then, after upgrading jenkins server, the new server won't ask you set password for admin user again. in fact it will use old creds only.
I have found the password in C:\Program Files\Jenkins\jenkins.err. Open jenkins.err text file and scroll down, and you will find the password.
Go to C:\Program Files (x86)\Jenkins\secrets
then with notepad ++ open file initail Admin Password and paste its content.
thats it
-->if you are using linux machine, then login as root user: sudo su
-->then go to the below path: cd /var/lib/jenkins/secrets
-->just view the IntialAdminPassword file ,you can see the secret key.
-->paste the secret key into jenkins window,it will be unlocked.
https://issues.jenkins-ci.org/browse/JENKINS-35981
Try this %2Fjenkins%2F instead of %2Fjenkins in the browser
Open the terminal on your mac and open new window (command+T)
Paste sudo cat /Users/Shared/Jenkins/Home/secrets/initialAdminPassword
It will ask for password, type your password(i gave my mac password, i haven't check if any other password would work) and enter
A key would be generated.
Copy the key and paste it where it asks you to enter admin password
click continue
The problem can be fixed in latest version: mine is 2.4. The error comes because of %2fjenkins%2f in URL. The previous version was coming with %2fjenkins and the same error used to come. They have resolved the issue, but the URL has been changed from %2fjenkins to %2fjenkins%. So as a summary in the URL currently %2fjenkins% is coming. before passing the admin password change it to %2fjenkins. Along with that add a .last_exec_version empty file.
If someone chooses running Jenkins as a Docker container, may face the same problem with me.
Because accessing-the-jenkins-blue-ocean-docker-container is quite different,
Common problem is /var/lib/jenkins/secrets: No such file or directory
You need to access through Docker, the link Jenkins provide is quite helpful.
Except <docker-container-name> maybe not specified, then you may need to use the container ID.
After
docker exec -it jenkins-blueocean bash
or
docker exec -it YOUR_JENKINS_CONTAINER_ID bash
The /var/lib/jenkins/secrets/initialAdminPassword would be accessible.
The password would be there.
I have setup Jenkins using Brew, But when I restarted Mac Jenkins was asking for initialAdminPassword(The screenshot attached in question)
And the problem was it was not generated under sercret directory.
So I'd found the Jenkins process which was running on port: 8080 using: $ sudo lsof -i -n -P | grep TCP and killed it using $ sudo kill 66(66 was process id).
Then I downloaded the latest jenkins .war file from: https://jenkins.io/download/
And executed command: $ java -jar jenkins.war (Make sure you are in jenkins.war directory).
And that's it everything is working fine.
This works well when you are stuck with Docker on Windows and are using Git-Bash
Presuming something like:
# docker run --detach --publish 8080:8080 --volume jenkins_home:/var/jenkins_home --name jenkins jenkins/jenkins:lts
Execute to get the Container ID, for example "d56686cb700d"
# docker ps -l
Now tell Docker to return the password written in the logs for that Container ID:
# docker logs d56686cb700d 2>&1 | grep -A5 -B5 Admin
2>&1 redirects stderr to stdout
-A5 includes 5 lines AFTER the line with "Admin" in it
-B5 includes 5 lines BEFORE the line with "Admin" in it
Output example:
Jenkins initial setup is required. An admin user has been created and a password generated.
Please use the following password to proceed to installation:
47647383733f4387a0d53c873334b707
This may also be found at: /var/jenkins_home/secrets/initialAdminPassword

Please use the following password to proceed to installation:
And paste it there in the jenkins prompt. Worked for me.
To solve this problem for docker container in Ubuntu 18.04.5 LTS (Bionic Beaver) - Ubuntu Releases
1- connect to your docker server or ubuntu server witch ssh or other method
2- run sudo docker ps
3- copy the container name parameter ("NAMES")
4- run sudo docker logs "your_parameters_NAMES_VALUES"
5- Find the folowing sentence "Jenkins initial setup is required. An admin user has been created and a password generated.

I'm developing for jailbroken devices, and have gotten Xcode building and debugging workin on device with a self signed certificate and some edits to Xcode.
But the app I'm developing requires being able to call setuid(0), thus it needs to have chmod +s in order to run properly.
Apart from this iOS apps that needs to run as root need a bash script to invoke it like such:
#!/bin/bash
dir=$(dirname "$0")
exec "${dir}"/App\ Binary_ "$#"
So, I need this build script to run on building my app:
cd ${BUILT_PRODUCTS_DIR}/My\ App.app/
mv App_Binary App_Binary_
cp /Users/john/Shellscript Binary_App
chmod +s Binary_App_
chmod +x Binary_App
I've tried adding this as a normal build script, and as a part of the scheme as both a Build post-action or a Run Pre-action. Neither which has worked. For example a post-action script on build returns that code signing failed, since it tries to codesign App Binary that is now the shell script. If I do it as a pre-action script on Run it displays "Xcode cannot run using the selected device.Choose a destination with a supported architecture in order to run on this device."
What should I do?
I use a post-action script to build my jailbreak apps. Although they don't need an additional chmod or bash script to run, you could use a script like mine to install your app (as a system app, not a normal App Store app) using ssh, then perform the chmod command and swapping the binary with a bash script on device via the post-action script.
You could try something along these lines (I tried to use the details from your script, but there may be one or two mistakes):
# copy binary
scp -P $PORT -r $BUILT_PRODUCTS_DIR/${WRAPPER_NAME} root#$IPOD://private/var/stash/Applications/${WRAPPER_NAME}/App_Binary_
# copy script
scp -P $PORT /Users/john/Shellscript root#$IPOD://private/var/stash/Applications/${WRAPPER_NAME}/Binary_App
# set special permissions
ssh -p $PORT root#$IPOD "chmod +s /private/var/stash/Applications/${WRAPPER_NAME}/Binary_App_"
ssh -p $PORT root#$IPOD "chmod +x /private/var/stash/Applications/${WRAPPER_NAME}/Binary_App"
Set IPOD and PORT as appropriate. ${WRAPPER_NAME} is the name of the app as saved on disk, with the .app extension.
Actually, this could be done if you need your app to be installed as a normal App Store app as well, you'd just need to find out where it's been installed to and adjust the paths as appropriate.
You'll obviously need to have SSH installed and activated on your device (available on Cydia).
