I am trying to push a node application to Bluemix using command
cf push <APP NAME> -c "node app.js"
The node app being pushed has few empty nested directories.
The app has an initialization code which needs those nested directories to exist. It uses them to copy and generate files in the runtime.
Problem :
When I push the app, the empty directories are not pushed[only other files and directories that are no empty are pushed] and hence when the application tries to locate it, it fail with
Error: ENOENT No such file or directory error.
The workaround is to add a random file to each of the directory[ so that they are no more empty] and then it gets pushed to the Bluemix(by Cloud Foundry).
Expectation :
How to push the empty directories while pushing an application to the Bluemix? These directories are empty initially but will be used later to generate and save file or documents when the app runs in Bluemix.
If you have resources that are being ignored when pushing and you don't want them to be ignored, create a .cfignore file and list them there with a ! at the start of their lines:
intermediateFileFolderToIgnore/
!tempFolderToNotIgnore/
You can find the syntax for cfignore/gitignore here.

I have an error message that I do know know who to fix regarding Mongodb Realm CLI.
https://docs.mongodb.com/realm/cli/realm-cli-apps-create/
When I write the following command in Terminal:
realm-cli apps init -n "test"
I get the error message "app init setup failed: a project already exists"
I have already had a project name "test" but I have deleted it (Simply deleting the folder which might have been the mistake) but I still get the error message. The error occurs always, no matter the name or path/folder at the moment.
if realm-cli push is used it seems to use the old "test" application since the name is filled out when going through the [options]
https://docs.mongodb.com/realm/cli/realm-cli-push/
If I push the application it will deploy the test application and if deleted through either CLI or GUI it returns to the first problem mention at the start.
Where to go from here? Is the application somehow stored as a draft or something making it impossible for me to create another before its discarded or am I missing something?
After sleeping (in lite account type) node-red, created by node-red starter kit, crashes while starting. It is possible to login in editor for a few seconds and then it crashes with error code "an instance of the app crashed: APP/PROC/WEB: Exite with status 1 (out of memory)". Dashboard (node-red-dashboard) was installed before sleeping and worked correctly.
I tried to restart Node-RED, Stop and Start.
I solved this problem. The problem may be due to the memory overflow in the container Garden. Taking into account that the content is stored in the cache, the application cannot start after the restart process, it issues an Exit status 1 (out of memory) error.
The cache is updated only by pushing the application into the cloud.
An option that was checked for application recovery:
View the name of the database for NodeRED (which stores all information about the Node-RED) in Cloudant, for example, "nodered."
Install to PC Cloud Foundry Command Line Interface - CLI https://docs.cloudfoundry.org/cf-cli/install-go-cli.html
Download from github and unarchive the application's code bluemix-starter https://github.com/knolleary/node-red-bluemix-starter (clone or download -> download zip)
In the downloaded folder add a record to a manifest file (manifest.yml) in the env section, in which set the database name (for example, nodered) in Cloudant to environment variable NODE_RED_STORAGE_DB_NAME. Four spaces must be made before NODE_RED_STORAGE_DB_NAME. It is better to make changes using the Notepad ++ editor.
---
applications:
- memory: 256M
env:
OPTIMIZE_MEMORY: true
NODE_RED_STORAGE_DB_NAME: nodered
command: node index.js --settings ./bluemix-settings.js –v
Save the file after changing.
Run the command line (cmd) and then:
a. go to a folder with a downloaded project, such as Windows
cd c:/node-red-bluemix-starter
b. specify the api endpoint where the application is located, in our case:
cf api https://api.eu-gb.bluemix.net
c. send a registration command in the cloud
cf login
d. specify the mail and password (password is entered without explicit character display)
e. pushing the project by specifying the name of your instance Node-RED, for example NameApp
cf push NameApp
I have created Azure Batch pool with Linux Machine and specified Application Package for the Pool.
My command line is
command='python $AZ_BATCH_APP_PACKAGE_scriptv1_1/tasks/XXX/get_XXXXX_data.py',
python3: can't open file '$AZ_BATCH_APP_PACKAGE_scriptv1_1/tasks/XXX/get_XXXXX_data.py':
[Errno 2] No such file or directory
when i connect to node and look at working directory non of the Application Package files are present there.
How do i make sure that files from Application Package are available in working directory or I can invoke/execute files under Application Package from command line ?
Make sure that your async operation have proper await in place before you start using the package in your code.
Also please share your design \ pseudo-code scenario and how you are approaching it as a design?
Further to add:
Seems like this one is pool level package.
The error seems like that the application env variable is either incorrectly used or there is some other user level issue. Please checkout linmk below and specially the section where use of env variable is mentioned.
This seems like user level issue because In case of downloading the package resource, if there will be an error it will be visible to you via exception handler or at the tool level is you are using batch explorer \ Batch-labs or code level exception handling.
https://learn.microsoft.com/en-us/azure/batch/batch-application-packages
Reason \ Rationale:
If the pool level or the task application has error, an error-list will come back if there was an error in the application package then it will be returned as the UserError or and AppPackageError which will be visible in the exception handle of the code.
Key you can always RDP into your node and checkout the package availability: information here: https://learn.microsoft.com/en-us/azure/batch/batch-api-basics#connecting-to-compute-nodes
I once created a small sample to help peeps around so this resource might help you to checkeout the use here.
Hope rest helps.
On Linux, the application package with version string is formatted as:
AZ_BATCH_APP_PACKAGE_{0}_{1}
On Windows it is formatted as:
AZ_BATCH_APP_PACKAGE_APPLICATIONID#version
Where 0 is the application name and 1 is the version.
$AZ_BATCH_APP_PACKAGE_scriptv1_1 will take you to the root folder where the application was unzipped.
Does this "exact" path exist in that location?
tasks/XXX/get_XXXXX_data.py
You can see more information here:
https://learn.microsoft.com/en-us/azure/batch/batch-application-packages
Edit: Just saw this question: "or can I invoke/execute files under Application Package from command line"
Yes you can invoke and execute files from the application package directory with the environment variable above.
If you type env on the node you will see the environment variables that have been set.
in Talend(data integration) i am trying to copy local directory to remote directory but when i am running the job only i can copy files but not folders from directory.please help me with this job.
In my talend job i am using local connection and remote connection components->
tfilelist->tfileproperties(to store path and name in one table)->tmssqlinput(extracting path from last table)->iteration-> tssh(if directory s not available then create)->finally sending it to tftpput to connect and copy to remote directory.
when i am storing in one table using tfileproperties in that for files it will generate some size but when folder s coming the size will be zero,using this condition m creating the directory using tssh component but unable to create folders,please help me.
Do you get an error message?
I believe the output of the TMSSqlInput should be a row based, rather than iteration. That might be the source of the problem.
tMSqlInput docs
tMSSqlInput executes a DB query with a strictly defined order which
must correspond to the schema definition. Then it passes on the field
list to the next component via a Main row link.
how can I change the directory where capistrano puts its log files? I could not find in the docs.
Currently the logs appear in myapp/log/... on my dev machine. However, since I am using laravel, and there is a log directory myapp/storage/logs I would like capistranos logs to appear here as well.
Do you mean the capistrano.log file that is created and appended to whenever you deploy?
You can specify the location by adding the following to deploy.rb:
set :format_options, log_file: "storage/logs/capistrano.log"
This tells Airbrussh (the default logging implementation in Capistrano 3.5.0+) where to place the log file. More information here: https://github.com/mattbrictson/airbrussh#configuration
