I'm trying to add a configuration file in /usr/share/logstash/config inside a docker run by kubernetes , I console onto the docker using $ kubectl exe -it "docker_name" -- /bin/bash.
I create then a .conf file in /usr/share/logstash/config/ , but when try to save the configurations it give me an error :
pipeline/input main.conf E166: Cant open linked file for writing.
I'm not sure if what I'm doing is right in beginning or there should be some better way to achieve this ?
Error E166 Can't open linked file for writing
You are trying to write to a file which can't be overwritten, and the file is a link (either a hard link or a symbolic link). Writing might still be possible if the directory that contains the link or the file is writable, but Vim now doesn't know if you want to delete the link and write the file in its place, or if you want to delete the file itself and write the new file in its place. If you really want to write the file under this name, you have to manually delete the link or the file, or change the permissions so that Vim can overwrite
You should use a ConfigMap to change the configfile

Im trying to install a JSON formatter for Cucumber but am having trouble configuring it. The steps (listed here) go like this:
1. Download cucumber-json-formatter-darwin-amd64 and rename it to cucumber-json-formatter
2. Move it to a directory that's on your PATH
3. Make it executable with chmod +x cucumber-json-formatter
4. Verify that you can run it: cucumber-json-formatter --help
I have the file downloaded and renamed correctly. However, I am stuck on the second step of moving it to a directory thats on my PATH.
Doing some research, I know what the folder structure looks like but I'm not sure exactly what the step is instructing. How would I achieve this step? Can it be in ANY directory on my PATH? I am currently using a Mac if that makes any difference for the solution.
Move it to a directory that's on your PATH
PATH refers to the machine's environment variable named PATH. Any time the OS is asked to execute something PATH is searched.
On Windows open System Properties dialog, click Environment Variables button and Path is listed there. You can add a new entry for the location of cucumber-json-formatter or you can move it to an existing Path entry.
Docker pull allows to pull directly ie. weblate/weblate
fine, but it is neccessary to create a docker-compose.overwrite.yml file with config to run
so, the question is: where to place that file, how to handle that topic? cannot find the location for that yml file (there should be also a docker-compose.yml file available)
additional information:
if done via cloning the weblate-docker repo, it is possible to add that file, but, is it also possible to do it when "just" pulling?
I hope you are having a great day!
I'm new to docker. I think my problem is related to docker's directory tree
My app writes to a file to /home/user directory and then after some time reads that file again.
I got this error from my app.
[error] a.a.OneForOneStrategy - /home/user/bkjw_eqvfohygvkaxoxc-small.jpg
java.nio.file.NoSuchFileException: /home/user/bkjw_eqvfohygvkaxoxc-small.jpg
My dockerized app is unable to create the file and read. I'm thinking that the Docker considers the directory /home/user/ as a absolute directory of host.
I thought that the container would write to /home/user directory within the container's directory tree.
So the question is :
How can I specify the path to write the file inside the containers directory tree?
Your understanding about the directory tree is correct. Application running inside a docker container would write to /home/user/ in the container's directory tree.
Your issue seems to be with permissions, your java application probably doesn't have the rights to write to /home/user/ within the container. Either you should change the ownership/rights of the directory you're wanting to write in, or a simple solution I did in such case was to create the directory I wanted to write in, within the java code.
like:
// Create volume directories explicitly so that they are created with correct owner
Files.createDirectories(Paths.get(dirPath));
You can set dirPath String to something like /home/user/mydir IF your requirement is not to write in /home/user/ specifically.
In Ansible, i need to take a parent directory or current path of file automatically, in some of chef framework we have chef::config,it ll take automatically file path.
e.g:
/tasks/main.yml:
name: execute cmd
command: python file.py
If I have my "file.py" in a tasks folder, I need to execute my playbook from that path only like: /home/playbook/roles/sample/tasks ,then only it taking a script file and running.Suppose when i run from root path i mean /home/playbook/ path,it shows "No such file or directory"
I have tried lookup(env,HOME), It just takes /home alone but not related to that file path.
So to take a current file path how to give in ansible???
Thanks
Answer from comments
script module will copy the file first and then run it. if you use roles, you should place scripts into roles/my_role/files folder.
I am using Sublime Text 2 while following Michael Hartl's Ruby on Rails Tutorial.
The specific portion of the tutorial to which I am referring can be found at http://ruby.railstutorial.org/book/ruby-on-rails-tutorial (ctrl+F "Listing 5.26").
I am able to create the spec/support file. However, when trying to create the spec/support/utilities.rb file, I receive the message "Unable to save ~/rails_projects/sample_app/spec/support/utilities.rb".
Does anyone know why this might be?
Someone on the Sublime Text forum seems to have had the exact same problem: http://www.sublimetext.com/forum/viewtopic.php?f=3&t=8570&p=36922#p36922
This issue sounds like it's a result of incorrect permissions or ownership of the folder. Change directories (cd) so you're outside of the folder where you're creating the .rb file and type:
ls -l
This terminal command lists the permissions attached to all files/folders in that directory. If "root" is listed as the folder owner, change its owner by typing:
sudo chown YOUR_COMP_USER_NAME FOLDER_NAME/
You should now be able to save files from inside that folder.
To diagnose this, first find out if it's an issue in Sublime or your file system:
Does that file already exist? Try looking for it on your file system (not using Sublime).
Verify that you have permission to write to that file. Use "ls -la" on the command line to show the file permissions.
Are you able to create and/or save that file using any different editor, for example TextMate, or Notepad?
The following sublime plugin fixed the Unable to save... bug
https://gist.github.com/3779601
The folder spec/support doesn't exist, and sublime won't create the missing folder, so it errors.
You just need to make the spec/support folder , then sublime will save the file.
I also highly recommend installing the AdvancedNewFile plugin ( Video of it action thanks to Jeffrey Way and NetTuts+ ) , which you can grab straight from Package Control.
It creates files, parent folders if needed, and if you try to create a file that already exists, it opens it instead.
This can happen if you are trying to create the file within a directory that does not currently exist. For ex. I was unable to save
~/rails_projects/sample_app/app/views/shared/_error_messages.html.erb
via the "subl" command from the Terminal because I was missing /shared/ folder. Hope that helps.
so #knice almost had it, I ran into the same problem with permission when starting my first rails project on mavericks.
as mentioned if you run ls -l you'll see your folder / files listed with their permissions
I solved this by changing ownership recursively with the following command from outside my project directory
sudo chown -Rv <your_username> <your_path_and_foldername>
for example if you're in your folder in terminal you should cd .. and then
sudo chown -Rv username ruby_proj/
the -R is for recursive meaning it will apply to all files and folder contained within the folder you specified, and the v after just produces verbose output, showing you which folder and file permissions have been changed.
Hope that helps someone else.
