I need to append to the PATH within a Windows Docker container, and I've tried many permutations.
ENV PATH=%PATH%;C:\\Foo\\bin
ENV PATH=$PATH;C:\\Foo\\bin
ENV PATH="%PATH%;C:\Foo\bin"
ENV PATH="$PATH;C:\Foo\bin"
RUN "set PATH=%PATH%;C:\Foo\bin"
None of these work: they don't evaluate the preexisting PATH variable.
What is the right syntax to append to the PATH? Can I even append to the PATH inside Docker? (I can on similar Linux containers)
Unfortunately ENV won't work, because windows environment variable work a little differently than linux. more info
As of now the only way to do this is through RUN
But you don't need to create a separate file to do this. This can be done by the following much simpler one line command:
RUN setx path "%path%;C:\Foo\bin"
You can set environment variables permanently in the container using a powershell script.
Create a powershell script in yout docker context (e.g. setpath.ps1 ) containing this:
[Environment]::SetEnvironmentVariable("Path", $env:Path + ";C:\Foo\bin", [EnvironmentVariableTarget]::Machine)
Add this script to your container dockerfile and RUN the script. Add something like this to your dockerfile:
ADD ./setpath.ps1 c:/MyScripts/setpath.ps1
RUN powershell -Command c:\MyScripts\setpath.ps1
[Environment]::SetEnvironmentVariable is a good way, but will not work in nanoserver.
The best choice is:
RUN setx path '%path%;C:\Foo\bin'
This worked for me:
USER ContainerAdministrator
RUN setx /M PATH "%PATH%;C:/your/path"
USER ContainerUser
As seen in the .net sdk Dockerfile: https://github.com/dotnet/dotnet-docker/blob/20ea9f045a8eacef3fc33d41d58151d793f0cf36/2.1/sdk/nanoserver-1909/amd64/Dockerfile#L28-L29
Despite all previous answers, I've faced an issue in some environments. Basically on a custom local test environment the setx using the %PATH%;C:\foo\bar way works even when the folder has spaces like C:\Program Files. That though didn't work when trying it on our production environment.
Checking what Microsoft do when they install the base packages on their own images it turns out a better and more reliable way is to use the command this way:
RUN setx /M PATH $(${Env:PATH} + \";${Env:ProgramFiles(x86)}\foo\bar\")
This way docker will be able to get the proper paths and properly update the PATH data.
Edit:
I've fixed the missing trailing \ in the command, thanks to Robin Ding :)
The following works for me in nanoserver-1809 (from this GitHub issue):
ENV PATH="$WindowsPATH;C:\Foo\bin"
My answer is similar to mirsik's but has no need for a separate script. Just put this in your Dockerfile
RUN $env:PATH = 'C:\Foo\bin;{0}' -f $env:PATH ; \
[Environment]::SetEnvironmentVariable('PATH', $env:PATH, [EnvironmentVariableTarget]::Machine)
When I use vim to update my environmental variables (in ~/.bashrc), PyCharm does not get the updates right away. I have to shut down the program, source ~/.bashrc again, and re-open PyCharm.
Is there any way to have PyCharm source the changes automatically (or without shutting down)?
When any process get created it inherit the environment variables from it's parent process (the O.S. itself in your case). if you change the environment variables at the parent level, the child process is not aware of it.
PyCharm allows you to change the environment variables from the Run\Debug Configuration window.
Run > Edit Configurations > Environment Variables ->
In my case pycharm does not take env variables from bashrc even after restarting
Pycharm maintains it's own version of environment variables and those aren't sourced from the shell.
It seems that if pycharm is executed from a virtualenv or the shell containing said variables, it will load with them, however it is not dynamic.
the answer below has a settings.py script for the virtualenv to update and maintain settings. Whether this completely solves your question or not i'm not sure.
Pycharm: set environment variable for run manage.py Task
I recently discovered a workaround in windows. Close Pycharm, copy the command to run Pycharm directly from the shortcut, and rerun it in a new terminal window: cmd, cmder, etc.
C:\
λ "C:\Program Files\JetBrains\PyCharm 2017.2.1\bin\pycharm64.exe"
I know this is very late, but I encountered this issue as well and found the accepted answer tedious as I had a lot of saved configurations already.
The solution that a co-worker told me is to add the environment variables to ~/.profile instead. I then had to restart my linux machine and pycharm picked up the new values. (for OSX, I only needed to source ~/.profile and restart pycharm completely)
One thing to be aware is that another coworker said that pycharm would look at ~/.bash_profile so if you have that file, then you need the environment variables added there
In case you are using the "sudo python" technique, be aware that it does not by default convey the environment variables.
To correctly pass on the environment variables defined in the PyCharm launch configuration, use the -E switch:
sudo -E /path/to/python/executable "$#"
This is simply how environment variables work. If you change them you have to re-source your .bashrc (or whatever file the environment variables are located in).
from dotenv import load_dotenv
load_dotenv(override=True)
Python-dotenv can interpolate variables using POSIX variable expansion.
With load_dotenv(override=True) or dotenv_values(), the value of a variable is the first of the values defined in the following list:
Value of that variable in the .env file.
Value of that variable in the environment.
Default value, if provided.
Empty string.
With load_dotenv(override=False), the value of a variable is the first of the values defined in the following list:
Value of that variable in the environment
Value of that variable in the .env file.
Default value, if provided.
Empty string.
I have Installshiled script which define CATALINA_HOME as environment Variable initially. same script after that execute the batch file service.bat that is using CATALINA_HOME. this file when executed display the error CATALINA_HOME is not define define correctly. as this variable is defined as environmental VARIABLE and pointing Tomcat Directory Properly. I thing the system require reboot to recognize environment Variables.Is there any way to define Environment that work directly without reboot. I am using 64 bit Windows 7.
I may be wrong but the script that you're running loads the env variables once when you start it so you won't get any new env variables added during the runtime of the script.
And in your script, if you just execute the batch file, it will use the same out dated env variables the script started with.
What I do is run 'cmd /k service.bat' This starts a new shell (with the updated env variables) and runs the batch file and terminates afterwards.
You shouldn't need to reboot between your install.
I am running Jenkins from user jenkins thats has $PATH set to something and when I go into Jenkins web interface, in the System Properties window (http://$host/systemInfo) I see a different $PATH.
I have installed Jenkins on Centos with the native rpm from Jenkins website. I am using the startup script provided with the installation using sudo /etc/init.d/jenkins start
Can anyone please explain to me why that happens?
Michael,
Two things:
When Jenkins connects to a computer, it goes to the sh shell, and not the bash shell (at least this is what I have noticed - I may be wrong). So any changes you make to $PATH in your bashrc file are not considered.
Also, any changes you make to $PATH in your local shell (one that you personally ssh into) will not show up in Jenkins.
To change the path that Jenkins uses, you have two options (AFAIK):
1) Edit your /etc/profile file and add the paths that you want there
2) Go to the configuration page of your slave, and add environment variable PATH, with value: $PATH:/followed-by/paths/you/want/to/add
If you use the second option, your System Information will still not show it, but your builds will see the added paths.
I kept running into this problem, but now I just add:
source /etc/profile
As the first step in my build process. Now all my subsequent rules are loaded for Jenkins to operate smoothly.
You can also edit the /etc/sysconfig/jenkins file to make any changes to the environment variables, etc. I simply added source /etc/profile to the end of the file. /etc/profile has all all of the proper PATH variables setup. When you do this, make sure you restart Jenkins
/etc/init.d/jenkins restart
We are running ZendServer CE which installs pear, phing, etc in a different path so this was helpful. Also, we don't get the LD_LIBRARY_PATH errors we used to get with Oracle client and Jenkins.
I tried /etc/profile, ~/.profile and ~/.bash_profile and none of those worked. I found that editing ~/.bashrc for the jenkins slave account did.
The information on this answer is out of date. You need to go to Configure Jenkins > And you can then click to add an Environment Variable key-value pair from there.
eg: export MYVAR=test would be MYVAR is the key, and test is the value.
I found two plugins for that.
One loads the values from a file and the other lets you configure the values in the job configuration screen.
Envfile Plugin — This plugin enables you to set environment variables via a file. The file's format must be the standard Java property file format.
EnvInject Plugin — This plugin makes it possible to add environment variables and execute a setup script in order to set up an environment for the Job.
On my newer EC2 instance, simply adding the new value to the Jenkins user's .profile's PATH and then restarting tomcat worked for me.
On an older instance where the config is different, using #2 from Sagar's answer was the only thing that worked (i.e. .profile, .bash* didn't work).
Couldn't you just add it as an environment variable in Jenkins settings:
Manage Jenkins -> Global properties > Environment variables:
And then click "Add" to add a property PATH and its value to what you need.
This is how I solved this annoying issue:
I changed the PATH variable as #sagar suggested in his 2nd option, but still I got different PATH value than I expected.
Eventually I found out that it was the EnvInject plugin that replaced my PATH variable!
So I could either uninstall EnvInject or just use it to inject the PATH variable.
As many of our Jenkins jobs use that plugin, I didn't want to uninstall it...
So I created a file: environment_variables.properties under my Jenkins home directory.
This file contained the path environment value that I needed:
PATH=$PATH:/usr/local/git/bin/.
From the Jenkins web interface: Manage Jenkins -> Configure System.
In that screen - I ticked the Prepare jobs environment option, and in the Properties File Path field I entered the path to my file: /var/lib/jenkins/environment_variables.properties.
This way every Jenkins job we have receive whatever variables I put in this environment_variables.properties file.
Jenkins also supports the format PATH+<name> to prepend to any variable, not only PATH:
Global Environment variables or node Environment variables:
This is also supported in the pipeline step withEnv:
node {
withEnv(['PATH+JAVA=/path/to/java/bin']) {
...
}
}
Just take note, it prepends to the variable. If it must be appended you need to do what the other answers show.
See the pipeline steps document here.
You may also use the syntax PATH+WHATEVER=/something to prepend /something to $PATH
Or the java docs on EnvVars here.
I only had progress on this issue after a "/etc/init.d/jenkins force-reload". I recommend trying that before anything else, and using that rather than restart.
On my Ubuntu 13.04, I tried quite a few tweaks before succeeding with this:
Edit /etc/init/jenkins.conf
Locate the spot where "exec start-stop-server..." begins
Insert the environment update just before that, i.e.
export PATH=$PATH:/some/new/path/bin
Add
/usr/bin/bash
at
Jenkins -> Manage Jenkins -> configure System -> Shell->Shell
executable
Jenkins use the sh so that even /etc/profile doesn't work for me
When I add this, I have all the env.
Solution that worked for me
source ~/.bashrc
Explanation
I first verified Jenkins was running BASH, with echo $SHELL and echo $BASH (note I'm explicitly putting #!/bin/bash atop the textarea in Jenkins, I'm not sure if that's a requirement to get BASH). sourceing /etc/profile as others suggested was not working.
Looking at /etc/profile I found
if [ "$PS1" ]; then
...
and inspecting "$PS1" found it null. I tried spoofing $PS1 to no avail like so
export PS1=1
bash -c 'echo $PATH'
however this did not produce the desired result (add the rest of the $PATH I expect to see). But if I tell bash to be interactive
export PS1=1
bash -ci 'echo $PATH'
the $PATH was altered as I expected.
I was trying to figure out how to properly spoof an interactive shell to get /etc/bash.bashrc to load, however it turns out all I needed was down in ~/.bashrc, so simply sourceing it solved the problem.
I tried all the things from above - didn't work for me.
I found two solution (both for SSH-Slave)
Go to the slave settings
Add a new environment variable
PATH
${PATH}:${HOME}/.pub-cache/bin:${HOME}/.local/bin
The "${HOME}" part is important. This makes the additional PATH absolute.
Relative path did not work for me.
Option II (pipeline-script)
pipeline {
agent {
label 'your-slave'
}
environment {
PATH = "/home/jenkins/.pub-cache/bin:$PATH"
}
stages {
stage('Test') {
steps {
ansiColor('xterm') {
echo "PATH is: $PATH"
}
}
}
}
}
On Ubuntu I just edit /etc/default/jenkins and add source /etc/profile at the end and it works to me.
Running the command with environment variable set is also effective. Of course, you have to do it for each command you run, but you probably have a job script, so you probably only have one command per build. My job script is a python script that uses the environment to decide which python to use, so I still needed to put /usr/local/bin/python2.7 in its path:
PATH=/usr/local/bin <my-command>
What worked for me was overriding the PATH environment for the slave.
Set: PATH
To: $PATH:/usr/local/bin
Then disconnecting and reconnecting the slave.
Despite what the system information was showing it worked.
I have Jenkins 1.639 installed on SLES 11 SP3 via zypper (the package manager).
Installation configured jenkins as a service
# service jenkins
Usage: /etc/init.d/jenkins {start|stop|status|try-restart|restart|force-reload|reload|probe}
Although /etc/init.d/jenkins sources /etc/sysconfig/jenkins, any env variables set there are not inherited by the jenkins process because it is started in a separate login shell with a new environment like this:
startproc -n 0 -s -e -l /var/log/jenkins.rc -p /var/run/jenkins.pid -t 1 /bin/su -l -s /bin/bash -c '/usr/java/default/bin/java -Djava.awt.headless=true -DJENKINS_HOME=/var/lib/jenkins -jar /usr/lib/jenkins/jenkins.war --javaHome=/usr/java/default --logfile=/var/log/jenkins/jenkins.log --webroot=/var/cache/jenkins/war --httpPort=8080 --ajp13Port=8009 --debug=9 --handlerCountMax=100 --handlerCountMaxIdle=20 &' jenkins
The way I managed to set env vars for the jenkins process is via .bashrc in its home directory - /var/lib/jenkins. I had to create /var/lib/jenkins/.bashrc as it did not exist before.
1- add to your profil file".bash_profile" file
it is in "/home/your_user/" folder
vi .bash_profile
add:
export JENKINS_HOME=/apps/data/jenkins
export PATH=$PATH:$JENKINS_HOME
==> it's the e jenkins workspace
2- If you use jetty :
go to jenkins.xml file
and add :
<Arg>/apps/data/jenkins</Arg>
Here is what i did on ubuntu 18.04 LTS with Jenkins 2.176.2
I created .bash_aliases file and added there path, proxy variables and so on.
In beginning of .bashrc there was this defined.
# If not running interactively, don't do anything
case $- in
*i*) ;;
*) return;;
esac
So it's checking that if we are start non-interactive shell then we don't do nothing here.
bottom of the .bashrc there was include for .bash_aliases
# Alias definitions.
# You may want to put all your additions into a separate file like
# ~/.bash_aliases, instead of adding them here directly.
# See /usr/share/doc/bash-doc/examples in the bash-doc package.
if [ -f ~/.bash_aliases ]; then
. ~/.bash_aliases
fi
so i moved .bash_aliases loading first at .bashrc just above non-interactive check.
This didn't work first but then i disconnected slave and re-connected it so it's loading variables again. You don't need to restart whole jenkins if you are modifying slave variables. just disconnect and re-connect.
If your pipeline is executed on the remote node that is connected via SSH, then actually Jenkins runs agent application that performs incoming actions.
By default zsh shell is used, not the bash (my Jenkins has version 2.346.3).
Furthermore jenkins-agent runs non-login shell which makes default PATH values even if you put some configuration to .zshrc. It will be skipped.
My choice is to put the following shebang at a script start
#!/bin/bash -l
-l option makes bash to run in the login mode and in this case bash performs configurations specified in /etc/profile and ~/.bash_profile.
If you run script in Jenkins pipeline it will look like:
steps {
sh '''#!/bin/bash -l
env
'''
}
I have Ruby and GIT installed on my windows box. To run GIT commands I am utilizing the GIT Bash. To run Ruby commands I am using the command line.
I have not been successful running GIT commands from the CMD line nor can I seem to run Ruby commands from inside the GIT Bash. I would love to be able to run commands for both GIT and Ruby from the GIT Bash (ideal) or at the least from the CMD line.
What is the best way to go about this?
I run git commands from the CMD session all the time.
Make sure your PATH environment variable includes the 'cmd' directory from a msysgit distro:
Path=C:\Path\To\Git\1.7.1\cmd
If not, add it in your session:
set PATH=%PATH%;C:\Path\To\Git\1.7.1\cmd
and you are done. Git and Ruby commands in your CMD shell.
The reverse (Ruby commands) is possible in a Git bash, by adding to the PATH a value like /c/path/to/Ruby/186-27/bin
To elaborate on VonC's answer of making Ruby available in Git-Bash.
All you have to do is add the path to your Ruby bin folder in your windows environment variables. It doesn't have to be in the format /c/path/to/ruby, it can be C:\Ruby193\bin.
Step by step for Windows 7:
Start
Search programs and files (default textbox after hitting the Start icon), Search for 'environment'
Select 'edit the system environment variables'
Click 'Environment Variables' (bottom right of the form)
Add to the 'System Variables' 'PATH' the following ';C:\Ruby193\bin' (without the single quotes)
Restart your shell
Make sure to close your git-bash shell and restart it to pick up the new environment variable.
Go to My Computer -> Properties -> Advanced system settings ->
Environment Variables
Add a New System variable. Variable name = RUBY_BIN. Variable
value = C:\Ruby193\bin (path may vary).
Add a New System variable. Variable name = MSYSGIT_BIN. Variable
value = C:\msysgit\bin (path may vary).
Append ;%RUBY_BIN%;%MSYSGIT_BIN% to Path variable, under System variables.
Restart shell.
This will allow you to run ruby, git or sh (Git Bash) commands from Command Prompt, as well as Ruby from Git Bash.
My personal setup uses msysgit and tortoisegit. I've found that using TortoiseGit's Pageant manager for the keys lets me use everything from any command line, including powershell. The only annoyance is I have to have pageant running with the keys added, which seem to clear on every reboot. Fortunately I don't reboot often.
The combined answer for VonC and Rots helped me to achieve the desired results.
However, since I was not familiar with editing environment variables, I must have accidentally overwritten the path for my nodejs files.
As a result my solution included adding the ruby path and the nodejs path to my user variables instead of the system.
I'm using a Windows 7 machine.
while installing ruby installer, select the option "Add ruby executables to your path" . Then all git/ruby commands will run from git bash.
