docker-redis

This is the procedure for creating a new docker machine, load redis container, load the data and connect/verify the installation.

Remove Docker machine (wish to remove machine)

z:\> docker-machine rm -f defaultVM
About to remove defaultVM
WARNING: This action will delete both local reference and remote instance.
Error removing host "defaultVM": exit status 1
Successfully removed defaultVM

Create Docker machine for hosting Redis

docker-machine create -d hyperv --hyperv-virtual-switch "Majestic LAN Virtual Switch" defaultVM

Configure environment

1. docker-machine ls - returns names of docker machines

z:\>docker-machine ls
NAME        ACTIVE   DRIVER   STATE     URL                        SWARM   DOCKER        ERRORS
defaultVM   *        hyperv   Running   tcp://192.168.1.211:2376           v18.02.0-ce

2. Get environment to specific docker machine

z:\>docker-machine env defaultVM
SET DOCKER_TLS_VERIFY=1
SET DOCKER_HOST=tcp://192.168.1.211:2376
SET DOCKER_CERT_PATH=C:\Users\Michael\.docker\machine\machines\defaultVM
SET DOCKER_MACHINE_NAME=defaultVM
SET COMPOSE_CONVERT_WINDOWS_PATHS=true
REM Run this command to configure your shell:
REM     @FOR /f "tokens=*" %i IN ('docker-machine env defaultVM') DO @%i

3. Set environment

z:\>& "C:\Program Files\Docker\Docker\Resources\bin\docker-machine.exe" env defaultVM | Invoke-Expression

4. Create the image, the container and deploy - createDocker.cmd

Execute the createDocker.cmd script in a command window.

z:\> createDocker.cmd
...

z:\>docker images prune -q
z:\>docker container prune -f
Total reclaimed space: 0B
z:\>docker stop redis-svr
redis-svr
z:\>docker rm -f redis-svr
redis-svr
z:\>docker image rm -f redisbase

5. List containers running on machine

z:\>docker ps -a
CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS              PORTS                    NAMES
66de7f65f072        redisbase           "docker-entrypoint.s…"   19 hours ago        Up 19 hours         0.0.0.0:6379->6379/tcp   redis-svrdocker ps -a

6. Inspect Host Machine

Make a note of the IP Address of the container - needed for the configuration file of the single page application.

z:\>docker-machine inspect defaultVM
{
    "ConfigVersion": 3,
    "Driver": {
        "IPAddress": "192.168.1.211",
        "MachineName": "defaultVM",
...

7. Inspect Container

z:\>docker inspect redis-svr

Troubleshooting

Docker section - verify configuration

Verify port on container using ID
z:\> docker port 7cc69388ef9e 6379/tcp
Error: No public port '6379/tcp' published for 7cc69388ef9e
Verify port on container using name
z:\>docker port redis-svr 6379/tcp
Error: No public port '6379/tcp' published for redis-svr
Get container environment
z:\>docker container exec redis-svr env
Redis-client -verify server is running
z:\>docker container exec -i redis-svr /usr/local/bin/redis-cli ping
PONG
Interactive shell - access to the container file system
z:\>docker container exec -t -i redis-svr /bin/bash

Redis section - verify configuration

Create a monitor for the Redis service
z:\>docker container exec -t -i redis-svr /bin/bash
/usr/local/bin/redis-cli client set name Monitor
/usr/local/bin/redis-cli monitor
List the clients connected to the Redis service
z:\>docker container exec -t -i redis-svr /usr/local/bin/redis-cli client list
Display information for the Redis service
z:\>docker container exec -t -i redis-svr /usr/local/bin/redis-cli info

Data section - Verify data installation/Configuration (within the container)

Verify the GEO data is loaded
z:\> docker container exec -t -i redis-svr /usr/local/bin/redis-cli geopos Texas Amoco
1) 1) "-95.19020587205886841"
   2) "29.23135112784979839"
Verify the Tasks data is loaded
z:\> docker container exec -t -i redis-svr /usr/local/bin/redis-cli lrange tasks 0 -1
Verify the State data is loaded
z:\> docker container exec -t -i redis-svr /usr/local/bin/redis-cli smembers states
Verify the State Airport data is loaded
z:\> docker container exec -t -i redis-svr /usr/local/bin/redis-cli geodist Massachusetts Cranland Crowhurst mi
"38.4314"
Verify the Call data is loaded
z:\> docker container exec -t -i redis-svr /usr/local/bin/redis-cli hgetall call
1) "name"
2) "Joe"
3) "company"
4) "Caterpillar"
5) "phone"
6) "3096551235"
7) "time"
8) "Thursday 09:00"
Verify a few State Airport list is loaded
z:\> docker container exec -t -i redis-svr /usr/local/bin/redis-cli smembers alabama
...lists 275 airports...

z:\> docker container exec -t -i redis-svr /usr/local/bin/redis-cli smembers wyoming
...lists 120 airports...
