I followed the steps in this tutorial to set up nodeJS web server in ubuntu-18-04.
Now what I should take into account while following this tutorial to set up postgres on another droplet in order to be able to connect to it from the other droplet?
Hi, I have successfully installed my app on Kubernetes cluster. But I observed my app was seeing the local IP instead of actual client IP. So I enabled proxy protocol in load balancer and installed nginx-ingress as follows: ``` # Installing the Kubernetes Nginx Ingress Controller helm install stable/nginx-ingress --name nginx-ingress --set controller.publishService.enabled=true,controller.config.use-forwarded-headers='"true"',controller.config.use-proxy-protocol='"true"' ``` But now I get the following error on accessing my API: ``` curl https://my-api.example.com/v3/status curl: (35) error:1400410B:SSL routines:CONNECT_CR_SRVR_HELLO:wrong version number ```
I have an app loading a fair amount of images like facebook. Larger png files take a bit longer to show up and download. I'm on the $10 a month plan running an nginx reverse proxy with Node and MySQL. Would something like s3 be better for image speed or do I just need to upgrade digital ocean and/or optimize things? Any recommendations would be greatly appreciated. Thanks. Keith
I have an application using Ionic, Angular & CouchDB. Can I run that on DigitalOcean. I've only seen the MEAN stack, not the CAN (Couch Angular Node) Stack
Dear community, I'm new to DigitalOcean and still lack experience. I set up a Droplet with RStudio on Ubuntu 18.04. To run my code, I need to install the "pcalg" package. However, I always get the following error messsage. Does anyone have an idea how to fix this? Your help would be much appreciated. ``` > install.packages("pcalg") Installing package into ‘/home/paul/R/x86_64-pc-linux-gnu-library/3.6’ (as ‘lib’ is unspecified) Warning in install.packages : dependencies ‘graph’, ‘RBGL’ are not available also installing the dependencies ‘V8’, ‘dagitty’ trying URL 'https://cloud.r-project.org/src/contrib/V8_2.3.tar.gz' Content type 'application/x-gzip' length 304765 bytes (297 KB) ================================================== downloaded 297 KB trying URL 'https://cloud.r-project.org/src/contrib/dagitty_0.2-2.tar.gz' Content type 'application/x-gzip' length 168082 bytes (164 KB) ================================================== downloaded 164 KB trying URL 'https://cloud.r-project.org/src/contrib/pcalg_2.6-2.tar.gz' Content type 'application/x-gzip' length 4859003 bytes (4.6 MB) ================================================== downloaded 4.6 MB * installing *source* package ‘V8’ ... ** package ‘V8’ successfully unpacked and MD5 sums checked ** using staged installation Using PKG_CFLAGS=-I/usr/include/v8 -I/usr/include/v8-3.14 Using PKG_LIBS=-lv8 -lv8_libplatform ------------------------- ANTICONF ERROR --------------------------- Configuration failed because was not found.
