I would like to change the default Kubernetes log format to "json" for system logs at "create" or preferably at "runtime".
The documentation designates the --logging-format=json for this purpose. However, I have been unable to identify what command-line call I would use to specific this flag.
I have tried kube-apiserver and kind cmd-line with no luck so far.
I am currently using Kind, but any reference related to Kube would be fine.
Questions:
Does this need be at "create" for the cluster?
If runtime is ok, what cmd util would I use to change a cluster configuration at runtime?
Do I need to apply a configuration with "kubectl" with a yaml file?
We have downloaded and installed a running instance of Wirecloud in our company server following the steps at:
https://conwet.fi.upm.es/wirecloud/install
We created the instance using the --quick-start command to try the instance, and ran wirecloud using the Django internal web server with the following command:
$ python manage.py runserver 0.0.0.0:8080 --insecure
We are able to enter the instance, and move around the enviroment, but we have encountered a problem when we try to upload a widget to our local workspace. After I search for the widget in my computer (previously downloaded from the Fi-lab marketplace), we get the next message:
Error adding packaged resource: Internal Server Error.
We also tried to download the zip file of the widget from github, unzip it and recompress it as a wgt file (compress as a zip but changing the extension to .wgt) and we get the same answer from our wirecloud instance; but if we try to upload the same package to the instance in fi-lab, it uploads successfully.
We don't know if it's because of the quick-start installation we made or if we have to modify something from our widget files in order to be able to upload it to our local instance.
Solved
The problem was in the config.xml file: the name of the attributes and the structure of the widgets unable to upload were different from the template of the config.xml file posted at the users guide.
After changing it to follow the structure of the template it works fine.
My widget example was the NGSI Updater. The thing is that it uploads perfectly in the instance at FiLab, even though the config.xml file had a different structure from the one of the template; but it encounters an error when uploading it to the Wirecloud local instance at my server.
I started a Django 1.7 OpenShift instance. When I have python print all of the paths from sys.path I do not see OPENSHIFT_REPO_DIR (/var/lib/openshift/xxxxx/app-root/runtime/repo).
When I use https://github.com/jfmatth/openshift-django17 to create a project I do see OPENSHIFT_REPO_DIR in the path.
Looking through the example app above I don't see anywhere that this is specifically added to the path. What am I missing?
To clarify:
I have to add the following to my wsgi.py:
import os
import sys
ON_PASS = 'OPENSHIFT_REPO_DIR' in os.environ
if ON_PASS:
x = os.path.abspath(os.path.join(os.environ['OPENSHIFT_REPO_DIR'], 'mysite'))
sys.path.insert(1, x)
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "mysite.settings")
OPENSHIFT_REPO_DIR is not in my path as I would expect. When I used the example git above, I did not have to add anything to the path.
A little while back I had issues with some of the pre-configured OpenShift environment variables not appearing until I restarted my application.
For what its worth, I started up a brand new Django gear, printed the environment variables to the application log, and verified that I do see OPENSHIFT_REPO_DIR (and all other env vars) properly.
This issue appears to be caused by trying to use the standard file structure layout that django produces when you use startproject. Openshift appears to need a flatter file structure. As soon as I moved wsgi up to a sibling of mysite it resolved the issue.
In a Windows environment, I'm trying to load a .csv file with statement:
LOAD CSV WITH HEADERS FROM "file:///E:/Neo4j/customers.csv" AS row
It seems not to work properly and returns:
Couldn't load the external resource at:
file:/E:/Neo4j/Customers.csv
Neo.TransientError.Statement.ExternalResourceFailure
What am I doing wrong? thanks in advance
I was getting this error on Community Edition 3.0.1 on Mac OS X 10.10
It appears that the LOAD CSV file:/// looks for files in a predefined directory. One would think that in the argument that one would give the Cypher statement the full path but that is not the case.
The file:/// - for my situation" meant that neo4j would append the given argument you gave to one that was already predefined and then go look for that combined path
The file:/// pre-defined directory directory did not exist entirely
/Users/User/Documents/Neo4j/default.graphdb/import, in my computers directory structure I was missing the "/import" folder, which was not created at install
To fix on my system, I created an "import" directory, put the file to be read in that directory. I executed the Cypher load statement I ONLY put the name of the file to be read in the file argument i.e.
LOAD CSV file:///data.csv
this worked for me.
It appears to be a security configuration. Here's the original answer I found: https://stackoverflow.com/a/37444571/327004
You can add the following setting in conf/neo4j.conf in order to bypass this :
dbms.security.allow_csv_import_from_file_urls=true
Or change the import directory dbms.directories.import=import
You can find the answer in the file
"C:\Users\Jack\AppData\Roaming\Neo4j Community Edition\neo4j.conf"
(above "dbms.directories.import=import")
For version neo4j-community_windows-x64_3_1_1 you have to comment out this line or you have to create the folder \import (which isn´t created through the installation) and add your file into the folder.
There it´s written that due to security reasons they only allow file load from the \Documents\Neo4j\default.graphdb\import folder
After commenting out on # dbms.directories.import=import , you can execute e.g. from
LOAD CSV FROM "file:///C:/Users/Jack/Documents/products.csv" AS row
In neo4j.conf I didn´t have to add/set
dbms.security.allow_csv_import_from_file_urls=true
On (Arch) Linux + neo4j-community-3.4.0-alpha09, edit $NEO4J_HOME/conf
/neo4j.conf:
uncomment or add: dbms.security.allow_csv_import_from_file_urls=true
comment: #dbms.directories.import=import
Restart neo4j (in terminal: neo4j restart), and reload the Neo4j Browser (http://localhost:7474/browser/) if you are using a web browser as your Neo4j interface/GUI.
Then, you should be able to load a csv from outside your $NEO4J_HOME/... directory
E.g.,
LOAD CSV WITH HEADERS FROM "file:///mnt/Vancouver/Programming/data/metabolism/practice/a.csv" AS ...
where my $NEO4J_HOME/ is /mnt/Vancouver/apps/neo4j/neo4j-community-3.4.0-alpha09/
LOAD CSV WITH HEADERS FROM "file:/mnt/Vancouver/Programming/data/metabolism/practice/a.csv" AS ...
also works, but not
LOAD CSV WITH HEADERS FROM "file://mnt/Vancouver/Programming/data/metabolism/practice/a.csv" AS...
or
LOAD CSV WITH HEADERS FROM "/mnt/Vancouver/Programming/data/metabolism/practice/a.csv" AS...
i.e. use ...file:/... or ...file:///...
It's probably an URL issue, try file:c:/path/to/data.csv
See my blog posts:
http://jexp.de/blog/2014/10/load-cvs-with-success/
http://jexp.de/blog/2014/06/load-csv-into-neo4j-quickly-and-successfully/
For the ubuntu system, I placed the file in /usr/lib/neo4j which helped me solved the issue. On every other location, i tried giving full permissions(777) but the problem remains the same. After going through another stackoverflow post, i realized that the file should be kept in neo4j directory.
In the Neo4j desktop select the database you are using, go to the setting and there you will find the solution... just comment the "dbms.directories.import=import" line
# This setting constrains all LOAD CSV import files to be under the import directory. Remove or comment it out to
# allow files to be loaded from anywhere in the filesystem; this introduces possible security problems. See the
# LOAD CSV section of the manual for details.
dbms.directories.import=import ### COMMENT THIS LINE
For macOS Mojave v 10.14.5
Actually, I had to uncomment dbms.directories.import=import from ~/Library/Application Support/Neo4j Desktop/Application/neo4jDatabases/database-e2dd2a9c-d450-4639-861b-1e7e42b56b31/installation-3.5.5/conf/neo4j.conf and restart the service. Then it worked. All files has to be placed in import directory.
Run command LOAD CSV WITH HEADERS FROM 'FILE:/<yourCSV>.csv' as l return l
I am using the Neo4j Desktop and as others have said, the default graph database has a predefined import location. You can find the location by using the UI. If you put the CSV into the import directory, then you can use the relative path directly from you load csv command
Neo4j version is 3.1.1, OS is win10.
For me, LOAD CSV would read from Neo4j_Database_Location/testDB/import/artists.csv.
At first, I put csv file on the path F:\code\java\helloworld\artists.csv, and my cypher sentence is
LOAD CSV FROM 'file:///F:\\code\\java\\helloworld\\artists.csv' AS line
CREATE(:Artist {name:line[1],year:toInt(line[2])})
Then I get the error message returned as follows:
Couldn't load the external resource at: file:/D:/Neo4j/db/testDB/import/code/java/helloworld/artists.csv
It means neo4j itself concat the file path.
"D:/Neo4j/db/testDB/import/" is the Neo4j database location, and the "code/java/helloworld/artists.csv" is the csv file location.
For example, I install Neo4j on the path D:\Neo4j\Neo4j CE 3.1.1, and database loaction is D:\Neo4j\db. I put the CSV file on the path D:\Neo4j\db\testDB\import\artist.csv. If you don't have the file folder "import" on the path, you should creat it by yourself and put your file in the folder "import".
Then, put your csv file in the path, and input cyper sentence:
LOAD CSV from 'file:///artist.csv' as LINE
CREATE(:Artist {name:line[1],year:toInt(line[2])})
In a word, once you put the CSV file in the right path, the problem can be solved.
Related explaination in the LOAD CSV developer-manal
If dbms.directories.import is set to the default value import, using the above URLs in LOAD CSV would read from /import/myfile.csv and import/myproject/myfile.csv respectively.
If it is set to /data/csv, using the above URLs in LOAD CSV would read from /data/csv/myfile.csv and /data/csv/myproject/myfile.csv respectively.
Set the Property "dbms.directories.import=import"
Create folder 'import' explicitly at "/Users/User/Documents/Neo4j/default.graphdb/" because pre-defined directory did not exist entirely
place the csv data set here in the import folder
then run the code like - LOAD CSV FROM "file:///C:/customers.csv" AS row
In addition after you run the line, you can analyze what is going wrong in the code section to get a better understanding
you put your dataset into the import directory in neo4j-community path.
Then re-run your command.
Add your csv file in the import folder of neo4j installation guide to do this.
open neo4j and start graph of ur project
then in open folders tab open import folders
Copy ur csv file in this folder
Copy that part in ur load syntax as file:///C:/neo4j_module_datasets/test.csv since ur neo4j in running
in C drive
Snapshot for your reference
Use the following syntax:
LOAD CSV WITH HEADERS FROM "file:///my_collection.csv" AS row CREATE (n:myCollection) SET n = row
If you are running a docker then, follow these commands before running above query:
docker run \
-p=7474:7474 \
-p=7687:7687 \
-v=$HOME/neo4j/data:/data \
-v=$HOME/neo4j/logs:/logs \
-v=$HOME/local_import_dir:/var/lib/neo4j/import \
neo4j:3.0
Then,
sudo cp my_collection.csv /home/bajju/local_import_dir/
One of the following should solve the LOAD CSV errors (assuming you have dbms.security.allow_csv_import_from_file_urls=true)
If using Linux check for the permissions for the file. Change it using chmod 777 file_name.csv
Check if the file format/format for the contents within the file is correct.
The easiest way (be ware of security) is to serve you directory over http and use the http import
in the command line go the folder where csv files are lcoated
run the following depending on your python env.
Python 2
$ python -m SimpleHTTPServer 8000
Python 3
$ python3 -m http.server 8000
- Now you can load your files from your local host
LOAD CSV FROM 'http://localhost:8000/mycsvfile.csv' AS row
return row
- you can actually expose files on one host and load them where your DB is running by exposing the folder and replacing localhost with your IP
Is it possible to open an sqlite file over http? I only need to read the db, and was hoping I could do something like:
var dbFile:File = new File("http://10.1.1.50/project/db.sqlite");
sqlConnection.open(dbFile);
Error #3125: Unable to open the database file.', details:'Connection closed.', operation:'open', detailID:'1001'
My situation calls for several apps compiled for various devices to share this file, which is served locally via wamp.
Zip your sqlite file from db.sqlite to db.zip. Load this zip file in flex using URLLoader and unzip it back in flex.
If not, you can also rename the file's extension to .xml, load it using httpservice or urlloader and once you get the result, you can rename the file's name back to .sqlite and start querying the file and it will work just fine.
There is no way you can achieve this over HTTP.
SqLite is a file and not a service/process that may be accessible via any port.
The best case scenario is when you have network access to the computer where the sqlite file is stored, like:
\\myserver\databases\mysqlitefile.db
...but this may work only on windows :(
You can adapt your code to use modsqlite http://modsqlite.sourceforge.net/#using
there's an apache module to allow remote sqlite access via http.
