Docker, ENOENT: no such file or directory - docker

I have a Storage constant that is used in a file called listingController.js
const storage = Storage({
keyFilename: "../key/keyname.json"
});
Everything works fine when I'm not using Docker but after I create a Docker image and deploy it on server I get the following error:
ENOENT: no such file or directory, open '/key/keyname.json'
at wrapError (/app/node_modules/gcs-resumable-upload/build/src/index.js:17:12)
at /app/node_modules/gcs-resumable-upload/build/src/index.js:235:19
at getToken (/app/node_modules/google-auto-auth/index.js:27:9)
at getAuthClient (/app/node_modules/google-auto-auth/index.js:233:9)
at <anonymous>
Here I see a problem that the '..' is ignored in front of the path which is why I think that file is not found.
Here is my project structure:
src
--- key
----- keyname.json
----- firebasekeyfilename.json
--- controller
----- listingController.js
----- firebaseController.js
I have tried all different combinations of file names and paths but I cannot get it to find that file.
Does anyone have a clue why this is happening?
In my firebaseController I have the following reference to a similar file in the same folder and it works fine.
var serviceAccount = require("../key/firebasekeyfilename");
The only difference is that the path is inside require() and I guess that requires a different path.
Been stuck with this for a couple of days now, any pointers would be appreciated, thank!

pyhdfs.HdfsIOException: Failed to find datanode, suggest to check cluster health. excludeDatanodes=null

I am trying to run hadoop using docker provided here:
https://github.com/big-data-europe/docker-hadoop
I use the following command:
docker-compose up -d
to up the service and am able to access it and browse file system using: localhost:9870. Problem rises whenever I try to use pyhdfs to put file on HDFS. Here is my sample code:
hdfs_client = HdfsClient(hosts = 'localhost:9870')
# Determine the output_hdfs_path
output_hdfs_path = 'path/to/test/dir'
# Does the output path exist? If not then create it
if not hdfs_client.exists(output_hdfs_path):
hdfs_client.mkdirs(output_hdfs_path)
hdfs_client.create(output_hdfs_path + 'data.json', data = 'This is test.', overwrite = True)
If test directory does not exist on HDFS, the code is able to successfully create it but when it gets to the .create part it throws the following exception:
pyhdfs.HdfsIOException: Failed to find datanode, suggest to check cluster health. excludeDatanodes=null
What surprises me is that my code is able to create the empty directory but fails to put the file on HDFS. My docker-compose.yml file is exactly the same as the one provided in the github repo. The only change I've made is in the hadoop.env file where I change:
CORE_CONF_fs_defaultFS=hdfs://namenode:9000
to
CORE_CONF_fs_defaultFS=hdfs://localhost:9000
I have seen this other post on sof and tried the following command:
hdfs dfs -mkdir hdfs:///demofolder
which works fine in my case. Any help is much appreciated.
I would keep the default CORE_CONF_fs_defaultFS=hdfs://namenode:9000 setting.
Works fine for me after adding a forward slash to the paths
import pyhdfs
fs = pyhdfs.HdfsClient(hosts="namenode")
output_hdfs_path = '/path/to/test/dir'
if not fs.exists(output_hdfs_path):
fs.mkdirs(output_hdfs_path)
fs.create(output_hdfs_path + '/data.json', data = 'This is test.')
# check that it's present
list(fs.walk(output_hdfs_path))
[('/path/to/test/dir', [], ['data.json'])]

CopyFiles with webpack-encore

i need to copy files from node_modules to a directory web/bundles/myBundle/components
But now i have an error :
Error: EISDIR: illegal operation on a directory, open '/srv/project/web/bundles/myBundle/components'
Encore
.setOutputPath('web/bundles/myBundle/')
.setPublicPath('/bundles/myBundle')
.addEntry('myBundle', './app.js')
.copyFiles({
from: './src/project/myBundle/Resources/public/components',
to: 'components',
});
I just need to copy files, i tried that but i dont want to specify addEntry because there's none (empty js file just to solve problem).
If you have any idea or solution, thx !
Change "to:" line to the following
to: 'components/[path][name].[ext]',
The elements in the square brackets are keywords that will be replaced with the real path/filename/extension of each file during the copy process
Final solution, and copy methods explanation (in Symfony project)
for example you got custom website template, you copy its assets into Symfony PROJECT assets/template-name/assets as normal configuration for webpack files to add
in webpack.config.js
.copyFiles(
{ from: './assets/vuesy/assets/images',
includeSubdirectories: true,
to: 'assets/images/[folder]/[name].[ext]',
context: 'assets/vuesy/assets/',
pattern: /.*/
}
)
and here is HOW to build proper folder structure in your public/build directory.
from: - is the place where files are - relative to - webpack.config.js, dont put / at the end but dont forget to use ./ at the begining (in this case assets folder is in the same directory as webpack.config.js)
to: your public/build is defined, from this place you starting build directory structure, add for example assets/images then use [folder] KEY, add / and tell what will be name for final file [name].[ext]
you can add own name for file by adding [myownname-foo-v1-][name] in this part. It generate myownname-foo-v1-realfilename.extension
context: - context is a place FROM WHERE you start digging and copying files..

How To Require Lua Socket?

I'm very new to lua development with file manipulation, and now trying to import the lua socket package into my project according to this post, but I can't run even the code below.
I guess the error message indicates I need to import not only the socket.lua but also .\socket\core (probably .dll, since it doesn't have core.lua), while a reply at the post suggested importing only the file.
I'm stuck in just the beginning... What do I have to do for the next step?
local function main()
local socket = require("socket")
end
main()
Exception in thread "main" com.naef.jnlua.LuaRuntimeException: ...n32.win32.x86_64\workspace\TestForCiv\src\socket.lua:13: module 'socket.core' not found:
no field package.preload['socket.core']
no file '.\socket\core.lua'
no file 'C:\Program Files\Java\jre1.8.0_151\bin\lua\socket\core.lua'
no file 'C:\Program Files\Java\jre1.8.0_151\bin\lua\socket\core\init.lua'
...(a bunch of no file errors continues)
Edit: I added the folder structure. Even I add the .dll file it returns the same error.
I don't know the details of you configuration, but try this
require ("src.socket")
you should require a module from the root path of the lib

How to read a data file at a package path on Lua 5.1

How to read a data file at a package path on Lua 5.1?
What I'm looking for is something like a io.read but at the package directory instead of the working directory (arg[0]), and without using hardcoded absolute paths. That would be something like dofile does, but without running the code, only reading it as a string.
Example:
I have a test folder, the current working directory of the test.lua script.
There's a package luapackage in another folder, somewhere specified at the LUA_PATHenviroment variable.
luapackage can:
require("luapackage.other_module");
dofile("other_module.lua").
But luapackage can't do:
io.read("data.txt")
io.read("luapackage/data.txt")
Sample structure:
+-test/
|
+-test.lua
+-luamodule/
|
+-data.txt
|
+-luamodule.lua
|
+-other_module.lua
For this example, test.lua only requires luamodule:
-- test.lua
local luamodule = require("luamodule")
And luamodule needs to read its modules and data files:
-- luamodule.lua
local other_module= dofile("other_module.lua") -- works
-- local other_module= require("luamodule.other_module") -- also works
local data = io.open("data.txt") -- fails
-- local data = io.open("luamodule/data.txt") -- also fails
It doesn't work because it searches for the file at the working directory (test) and not the package directory.
If I place a copy of the package at running script's folder, io.read(luapackage/data.txt) is possible. But every script would have to carry its own local copy of luapackage.
Note: I'm looking for a Lua solution, avoiding binary packages that could compromise cross-compatibility.
You can use debug.getinfo(1,"S").source to get the location of the current (module) file. Replace luamodule.lua with data.txt, remove leading #, and you should get the path you need.

Yeoman - How to extract zipped files in generator?

I want to build a Yeoman generator that needs to unzip a file.
From their documentation, it seems this process is done using this.registerTransformStream(...). It says it accept any gulp plugin, so I tried gulp-unzip (link)
Here's my code:
// index.js
...
writing: function() {
var source = this.templatePath('zip'); // the folder where the zipped file is
var destination = this.destinationRoot();
this.fs.copy(source, destination);
this.registerTransformStream(unzip() );
}
...
The result seems promising, first it shows all the file list then I get Error: write after end error.
Here's the dump:
create license.txt
create readme.html
create config.php
...
...
events.js:141
throw er; // Unhandled 'error' event
^

The destination folder is empty after this. It seems the stream is trying to write the unzipped file but failed.
Does anyone solved this problem before? Or is there alternative way by just using the built-in fs?
Thanks a lot
