A daemon (background process) in python / VM/ Container / Docker Build for Deep Learning Model
A daemon can be used to keep a connection open.
import socket
s = socket.socket()
host = ‘xx.xxx.xxx.xx’ # ip addr needs to be in quote
port = xxxx # an open port
s.connect((host, port))
print (s.recv(xxxx)) # a port number
inpt = raw_input(‘type anything and click enter… ‘)
s.send(inpt)
print( “the message has been sent”)

Combining different container builds. Dockerfile successfully built an image , size 1.41 GB, using this dockerfile.
The image size is larger than the RAM on nanonode on cloud services which has 1 GB ram. This VM was created with 3 GB RAM.
Would have to upgrade compute instance: https://www.linode.com/pricing/#compute-shared
Considering CI/CD, i.e. Continuous Development / Continuous Integration, development, when do we have to restart a virtual machine, a container, a container, or a daemon if there is a reconfiguration? For what types of reconfigurations do we have to restart, and what types of changes can be implemented without restarting?
In web applications: User input displays on an HTML page.
- The HTML page is generated by .py file that reads the user input from a database. — In this case the new user input is not immediately displayed, the .py file has to run again.
- HTML action can support rendering information without regeneration. Delineate the information flow for this.
E ncryption of Docker Files / Containers / Volumes
Transition from launching 50 containers to 5000 containers
Considerations:
- Assigning port and ip addressses
Cron job vs. event handler. If the event frequency is unpredicatable, event handler (?).

Check which python processes are running: ps aux | grep python
Which ports are running: netstat -tuln
which program is listening on a particular port, such as 3000
sudo lsof -i :3000

Do pid’s, process id’s get re-assigned by OS for the same process if RAM is being competed for? How does OS manage pids. Can we refer to a process by $pid in a bash script?
# View the current maximum PID value
cat /proc/sys/kernel/pid_max
- There are outdated dependencies in the installation. install with — no-dep. installed dependencies separately. One file, spawn.py, had an incompatible syntaxt when copy/pasting.
- Spacy, mitie, total_word_feature_extractor.dat contribute to coherent, context accurate response.
- DIET (dual intent and entity transformer) is an intermediary.
