HealthChecker | Exchange Server Performance Health Checker Script | Command Line Interface library

For temporary answer that I used: put a cron to check the current status of server and run the script

current server status command line

The remote IP address is not passed to the gateway by default. To use the external IP address in your AuthorizationPolicy you can change the externalTrafficPolicy of the Ingress gateway. For testing you can use the following:

kubectl patch svc istio-ingressgateway -n istio-system -p '{"spec":{"externalTrafficPolicy":"Local"}}'

If this works you should add this to your IstioOperator (or create one) and apply it when installing Istio.

If you don't want to change the TrafficPolicy you might be able to accomplish it by using remoteIpBlocks instead of ipBlocks in the AuthorizationPolicy. But I did not try this yet myself, for reference: https://istio.io/latest/docs/tasks/security/authorization/authz-ingress/#ip-based-allow-list-and-deny-list

Validate that Beanstalk is running the latest version of your code. May still be using a container spun up before you added the new mappings.

network_mode: host doesn't work on MacOS or Windows systems. The Docker Use host networking documentation notes:

The host networking driver only works on Linux hosts, and is not supported on Docker Desktop for Mac, Docker Desktop for Windows, or Docker EE for Windows Server.

It also essentially entirely disables Docker's networking stack, and is almost never necessary.

You need to do three things here:

1. Remove all of the network_mode: host lines from the Compose file. (The container_name: lines are also unnecessary.)
2. For any of the services you need to access from outside Docker (could be all of them and that's fine) add ports: to publish their container ports.
3. When any of these services internally call other services configure their URLs (for example, in the .env files) to use their Compose service names. (See Networking in Compose in the Docker documentation.) (Also note that your frontend application probably actually runs in a browser, even if the code is served from a container, and can't use these host names at all; this specific point needs to still use localhost or the host name where the system will eventually be deployed.)

So, for example, the setup for the frontend and backend containers could look like:

Instead of passing the function to the template - you could pass only the dictionary. Then you could easily use it and iterate through it using jinja in your html file.

I can now see the services in kibana console. The errors where values of :

-Delastic.apm.service_name and -Delastic.apm.application_packages

Based on the comments.

The template is fine. The ALB does not work because it is placed in private subnets along with ECS service. Assuming that private subnets are correctly setup to work with NAT gateway and access the internet, the following should be made:

• Place ALB in public subnets - it must be there, as otherwise it will no be accessible from the internet.

Also double check all the route tables for NAT, public subnets, internet gateway.

CLB can't redirect from HTTP to HTTPS:

Classic Load Balancers can't redirect HTTP traffic to HTTPS

If you want to use CLB, all SSL and HTTPS handling must be done on the instances which is troublesome, puts more stress on the instances and its one more thing to manage yourself.

The easiest way to enable HTTPS and redirections from HTTP->HTTPS is through ALB, as explained in

• How can I redirect HTTP requests to HTTPS using an Application Load Balancer?

Grok pattern on line 32 is the issue. Need to escape all " characters. Below is an escaped version of the GROK.
