-# Fuge Examples
-This repository contains example systems, demonstrating the use of Fuge. To run the examples, clone this repository. Each example comes with it's own README.md and setup instructions. Each example builds on the next so it is advisable to run them in order.
 
-The examples are as follows:
+# External service
 
-## hello-world
-The simplest possible configuration. Runs a single service in the fuge shell.
+This example is the same as the External service example but it has extra some extra services. This shows how services can be grouped, so that commands can be applied to the whole group. Adderservice minusservice multiplyservice and divideservice all have a common group, [group: sums] created in the fuge.yml file.
 
-## simple-system
-A simple system system configuration with a front end and a single microservice.
+These groups can be seen using the ps command. You can apply all the usual commands to groups, eg, you can start the sums group hee with:
 
-## kubernetes-emulation
-A slightly more complex microservice system that emulates a production Kuberntes environment. This example has a front end and two services one of which reads and writes to a mongo database which is provided through the use of a docker mongo container.
 
-## using-docker-compose
-The same system as in the previous example but one service and the mongo container are configured using a docker compose file that is included in the fuge configuration. Demonstrates how to use compose file in conjunction with fuge.
+```sh
+$ fuge shell fuge/fuge.yml
+fuge> start sums
+fuge>ps
+```
 
-## services-and-infrastructure
-This example demonstrates how to keep infrastrcutre, i.e. databases, queuing systems etc.. running in the background with docker-compose but still have them discoverable to microservices managed with fuge. This is a useful pattern when killing and restarting the fuge shell.
+name                          type           group          status         watch          tail
+mongo                         container      default        not managed
+adderservice                  process        sums           running        yes            yes
+minusservice                  process        sums           running        yes            yes
+multiplyservice               process        sums           running        yes            yes
+divideservice                 process        sums           running        yes            yes
+auditservice                  process        default        stopped        yes            yes
+importantauditservice         process        critical       stopped        yes            yes
 
-## external-service
-This example demonstrates how to connect shared infrastructure in development. For example, in some development teams a shared database is used for development. This example builds on the `services-and-infrastructure` example and introduces an additional shared database system through an external DNS record set that allows services to discover this databse as they would in production using DNS.
 
 
+All commands that work with 'all', will also work with groups. 
+
+  Start, restart, stop, pull, status, tail, grep, etc.
+
+
+
+If you don't create a group for a service in the fuge.yml file then it will be given an automatic group of default, by default.

+# Fuge Changing Environment Variables
+
+# To change a value in memory:
+
+
+Start the shell by running "fuge shell fuge/fuge.yml"
+
+
+Run setval <process> to see all the available variables and their values, for example:
+
+fuge> setval adderservice
+
+        variables in adderservice
+        type = process
+        path = c:\MAMP\htdocs\fuge\fuge-examples\change-variables-while-running\adderservice
+        run = node service.js
+        ports = adderservice,8087,
+        name = adderservice
+        specific =
+        status = enabled
+        environment = ADDERSERVICE_SERVICE_HOST,127.0.0.1,ADDERSERVICE_SERVICE_PORT,8087,ADDERSERVICE_PORT,tcp://127.0.0.1:8087,ADDERSERVICE_PORT_8087_TCP,tcp://127.0.0.1:8087,ADDERSERVICE_PORT_8087_TCP_PROTO,tcp,ADDERSERVICE_PORT_8087_TCP_PORT,8087,ADDERSERVICE_PORT_8087_TCP_ADDR,127.0.0.1,WEBAPP_SERVICE_HOST,127.0.0.1,WEBAPP_SERVICE_PORT,3006,WEBAPP_PORT,tcp://127.0.0.1:3006,WEBAPP_PORT_3006_TCP,tcp://127.0.0.1:3006,WEBAPP_PORT_3006_TCP_PROTO,tcp,WEBAPP_PORT_3006_TCP_PORT,3006,WEBAPP_PORT_3006_TCP_ADDR,127.0.0.1,SERVICE_HOST,127.0.0.1,SERVICE_PORT,8087
+        host = 127.0.0.1
+        tail = true
+        monitor = true
+        monitor_excludes = 0,**/node_modules/**,1,**/.git/**,2,*.log
+        delay_start = 0
+        restart_on_error = false
+
+
+Run setval <process> <variable> to see a single variable, for example:
+
+        fuge> setval adderservice delay_start
+        delay_start = 0
+
+We can run setval <process> <variable> <value> to set a new value for the variable:
+
+        fuge> setval adderservice delay_start 3000
+        Old value = 0
+        New value = 3000
+
+Run setval with the env argument to set a new environment value for an enviornment variable <process> env <variable> <value> , for excample:
+
+        fuge> setval adderservice env SERVICE_PORT 8088
+        Old value = 8087
+        New value = 8088
+
+
+###############################################
+
+
+# To change a value from the fuge.yml file while Fuge is running:
+
+
+Start the shell by running "fuge shell fuge/fuge.yml"
+
+change a value in the yml file:
+
+        adderservice:
+        type: process
+        path: ../adderservice
+        run: 'node service.js'
+        terminate: SIGINT
+        ports:
+            - adderservice=8087
+
+Here we could change SIGINT to SIGTERM, change the port number, change the path, or add new properties and values .
+Note: Changing the path will disable the service if an invalid path is entered, but the system will keep running. Another way to disable a service is to use setval (above) to set the status to disabled.
+
+
+ So, after changing the fuge.yml file and saving the changes, run 'rel' to reload the changed values, and type 'y' to confirm, or 'n' to cancel:
+
+fuge> rel
+There are changed values in:  adderservice
+Do you want to apply these changes? (y/n)
+y

+# External service
+
+This example is the same as the External service example but it has extra some extra services. This shows how services can be grouped, so that commands can be applied to the whole group. Adderservice minusservice multiplyservice and divideservice all have a common group, [group: sums] created in the fuge.yml file.
+
+These groups can be seen using the ps command. You can apply all the usual commands to groups, eg, you can start the sums group hee with:
+
+
+```sh
+$ fuge shell fuge/fuge.yml
+fuge> start sums
+fuge>ps
+```
+
+name                          type           group          status         watch          tail
+mongo                         container      default        not managed
+adderservice                  process        sums           running        yes            yes
+minusservice                  process        sums           running        yes            yes
+multiplyservice               process        sums           running        yes            yes
+divideservice                 process        sums           running        yes            yes
+auditservice                  process        default        stopped        yes            yes
+importantauditservice         process        critical       stopped        yes            yes
+
+
+
+All commands that work with 'all', will also work with groups. 
+
+  Start, restart, stop, pull, status, tail, grep, etc.
+
+
+
+If you don't create a group for a service in the fuge.yml file then it will be given an automatic group of default, by default.
