aws codebuild / using local redis (ubuntu image) - amazon-web-services

Question

Getting into code build; currently looking to use redis on a local ubuntu image;
using the following script :
version: 0.2
phases:
install:
commands:
- apt update
- apt install -y redis-server wget
pre_build:
commands:
- wget https://raw.githubusercontent.com/Hronom/wait-for-redis/master/wait-for-redis.sh
- chmod +x ./wait-for-redis.sh
- service redis-server start
- ./wait-for-redis.sh localhost:6379
build:
commands:
- redis-cli info
- redis-cli info server
For now it seems to us that docker-compose is not ultimately required, we would first look into using it that way - expecting a standard ubuntu behaviour.
We're installing postgres with a similar approach, it does start properly and is fully usable.
Here we're unable to start redis properly, wait-for-redis keeps retrying (keep getting error Could not connect to Redis at localhost:6379: Connection refused)
With an ec2 linux image (yum based), we don't have such issue
What would be the correct way start redis in that ubuntu context ?

Answer 1

Just ran into the same problem.
When I added a cat /var/log/redis/*.log to the buildspec I discovered that Redis was not able to bind:
Creating Server TCP listening socket ::1:6379: bind: Cannot assign requested address
Further research showed this to be a known issue: https://github.com/redis/redis/issues/3241
... which can be fixed by adding these lines to the buildspec (before using redis):
- sed -i '/^bind/s/bind.*/bind 127.0.0.1/' /etc/redis/redis.conf
- service redis-server restart
