Azure Web App - Deploying Manually through ssh terminal - node.js

I've recently deployed a NodeJs Azure Web App and using Git to trigger the deployments when I make changes to the source code. Out of curiosity I was exploring the file system of the Linux server that's running the app and found the script file that's used for deployment (deploy.sh).
Is it possible to run that script file locally on the server while in an ssh session? For example if I wanted to make a change directly on the server to a file, instead of having to push the changes up through git (probably not a good idea but I want to know if it's possible regardless).
I tried running the script whilst in the directory where it's located but it failed to find the kudu sync command, which I thought was strange.
Cheers.

yes you can run the deploy.sh file. If i am not wrong then you might be getting some error like --- can not be sub directory of each other. In this case you can try to run the deplo.sh from inside the wwwroot folder. Let me know if it works.

How can I deploy my nodejs app into openshift without using github?

I have built a nodejs app and now I want to deploy it into openshift.
I don't want to use github because I should create private repository which I cannot.
Also I cannot use 'rhc' since I am new user.
Is there any way to do that?
I cannot find any tutorial about that.
For OpenShift 3, you can use a binary input source build.
First create a binary input build.
oc new-build --name myapp --strategy=source --binary --image-stream=nodejs:latest
Now start a new build and upload source code from the current directory.
oc start-build myapp --from-dir=.
Once the build has completed, deploy the image created by the build.
oc new-app myapp
You can then expose the service.
oc expose svc/myapp
Every time you want to make a change, you will need to run the same oc start-build command in the directory where your source code is.
Is there any other code repo you are using? SVN? If SVN, you can use pipelines with Jenkins.
If not, put the nodejs app in a docker container and push it to the docker hub.
I don't see anybody to suggest this so I will do - you can equally well deploy code from gitlab, pagure, bigbucket, or any other git hosting service.
In fact you can even run your own git server inside OpenShift.
oc create -f https://raw.githubusercontent.com/openshift/origin/master/examples/gitserver/gitserver-persistent.yaml
oc env dc/git -p ALLOW_ANON_GIT_PULL=false
oc policy add-role-to-user edit -z git
oc get route # to see your git server URL
Now you should be able to push/pull from that server using your OpenShift username and token (also any other users you add to the project). From buildconfigs and other pods you can also use simply git as the hostname of your git server, because this should resolve to the IP of the service with the same name (again only within the same OpenShift project).
Read the template YAML (the URL after oc create) for more options you can use like REQUIRE_GIT_AUTH.
Of course it is good to keep a git mirror/backup somewhere else as with any other git service.
HTH
P.S. Forgot to say, you need to install an OpenShift v3 cluster by yourself or subscribe to OpenShift Online (which unfortunately may take awhile ATM).

Azure Docker Container - how to pass startup commands to a docker run?

Faced with this screen, I have managed to easily deploy a rails app to azure, on docker container app service, but logging it is a pain since the only way they have access to logs is through FTP.
Has anyone figured out a good way to running the docker run command inside azure so it essentially accepts any params.
in this case it's trying to simply log to a remote service, if anyone also has other suggestions of retrieving logs except FTP, would massively appreciate.
No, at the time of writing this is not possible, you can only pass in anything that you would normally pass to docker run container:tag %YOUR_STARTUP_COMMAND_WILL_GO_HERE_AS_IS%, so after your container name.
TLDR you cannot pass any startup parameters to Linux WebApp except for the command that needs to be run in the container. Lets say you want to run your container called MYPYTHON using the PROD tag and run some python code, you would do something like this
Startup Command = /usr/bin/python3 /home/code/my_python_entry_point.py
and that would get appended (AT THE VERY END ONLY) to the actual docker command:
docker run -t username/MYPYTHON:PROD /usr/bin/python3 /home/code/my_python_entry_point.py

How to Deploy MEAN stack to my hosted server?

I have a great working website built with MEAN and works great locally.
i wish to deploy it on my server,
but i never deployed a website
other than uploading the files to my website ftp.
Tutorials anyone?
Another good starting point would be Digital Ocean, they offer a one click install MEAN stack, with tutorials. https://www.digitalocean.com/community/tutorials/how-to-use-the-mean-one-click-install-image
I have just deployed my MEAN Stack application on Heroku cloud application environment. The deployment steps are easy.
Steps to deploy:
Your mean stack project structure should be like this. This is very important step. The bottonline is your package.json and server.js should be under your root directory. Have a look at the link to know more about the structure.
Clone your remote repository locally i.e. git clone https://github.com/heroku/node-js-getting-started.git
Go inside the cloned repository e.g. cd node-js-getting-started
Run git add .
Run git commit -m "Sample"
Run Heroku login (It will ask you to press any key and then open up the browser and ask you to click login. After logged in closed the browser instance.
Run heroku create myApp --buildpack heroku/nodejs. Note: Buildpacks are responsible for transforming deployed code into a slug, which can then be executed on a dyno. More information
Run git push heroku master. Your deplyment will start.
Once deployment is done, you will see the complete deployment logs on command prompt terminal
The application is now deployed. Ensure that at least one instance of the app is running: heroku ps:scale web=1
Run heroku open. It will run your deployed instance.
Run heroku logs to view information about your running app. More information
You can find more details visiting following links:

How to simultaneously deploy Node.js web app on multiple servers with Jenkins?

I'm gonna deploy a Node.js mobile web application on two remote servers.(Linux OS)
I'm using SVN server to manage my project source code.
To simply and clearly manage the app, I decided to use Jenkins.
I'm new to Jenkins so it was a quite difficult task installing and configuring Jenkins.
But I couldn't find how to set up Jenkins to build remote servers simultaneously.
Could you help me?
You should look into supervisor. It's language and application type agnostic, it just takes care of (re-) starting application.
So in your jenkins build:
You update your code from SVN
You run your unit tests (definitely a good idea)
You either launch an svn update on each host or copy the current content to them (I'd recommend this because there are many ways to make SVN fail and this allows to include SVN_REVISION in the some .JS file for instance)
You execute on each host: fuser -k -n tcp $DAEMON_PORT, this will kill the currently running application with the port $DAEMON_PORT (the one you use in your node.js's app)
And the best is obviously that it will automatically start your node.js at system's startup (provided supervisor is correctly installed (apt-get install supervisor on Debian)) and restart it in case of failure.
A node.js supervisord's subconfig looks like this:
# /etc/supervisor/conf.d/my-node-app.conf
[program:my-node-app]
user = running-user
environment = NODE_ENV=production
directory = /usr/local/share/dir_app
command = node app.js
stderr_logfile = /var/log/supervisor/my-node-app-stderr.log
stdout_logfile = /var/log/supervisor/my-node-app-stdout.log
There are many configuration parameters.
Note: There is a node.js's supervisor, it's not the one I'm talking about and I haven't tested it.
per Linux OS, you need to ssh to your hosts to run command to get application updated:
work out the workflow of application update in shell script. Especially you need to daemonize your node app so that a completed jenkins job execution will not kill your app when exits. Here's a nice article to tell how to do this: Running node.js Apps With Upstart, or you can refer to pure nodejs tech like forever. Assume you worked out a script under /etc/init.d/myNodeApp
ssh to your Linux OS from jenkins. so you need to make sure the ssh private key file has been copied to /var/lib/jenkins/.ssh/id_rsa with the ownership of jenkins user
Here's an example shell step in jenkins job configuration:
ssh <your application ip> "service myNodeApp stop; cd /ur/app/dir; svn update; service myNodeApp restart"

Where to place node.js files on server?

I have just gotten a VPS to bring my first node.js project online, but I am wondering where do I place the node files like app.js if I want it to be accessible at http://www.mywebsite.com:3000?
Right now, to host a website, I am using WHM to create a cPanel account, which creates /home/cpanelusername and my HTML/PHP files all go into /home/cpanelusername/public_html. Where does node.js files go to? Or did I get this step wrong as well?
On my Mac where I developed the node app, I simply cd into the directory containing the node file and run node app.js
You have to execute app.js file using the node binary, just like you do in local development. That means that you should probably make that execution a service call, the details of which depend on your linux distro. If it's not a service call, then executing it in ssh will mean that the app stops working once you log out of ssh.
For example, in Ubuntu server (which I use) I have an Upstart script which automatically runs my node.js app automatically on system start and log to /var/log. An example of the file, named /etc/init/myapp.js.conf is:
description "myapp server"
author "Me"
# used to be: start on startup
# until we found some mounts weren't ready yet while booting:
start on started mountall
stop on shutdown
script
# We found $HOME is needed. Without it we ran into problems
export HOME="/root"
exec node /home/me/myapp/myapp.js 2>&1 >> /var/log/myapp.log
end script
Replace names, etc. as necessary.
Edit to add: You can then start and stop your service by running:
sudo start myapp.js or sudo stop myapp.js
