amc, aerospike are not recognized inside docker container

Question

I've docker ubuntu 16.04 image and I'm running aerospike server in it.

$ docker run -d -p 3000:3000 -p 3001:3001 -p 3002:3002 -p 3003:3003  -p 8081:8081  --name aerospike aerospike/aerospike-server

The docker container is running successfully.

$ docker ps

I've logged into the docker container

$ docker exec -it b0b4c63d7e22 bash

I have listed the directories -

I changed the directory to bin folder and listed the commands

Then I want to check the service -

root@b0b4c63d7e22:/bin# service amc status
amc: unrecognized service

Answer 1

Aerospike's official docker container does not have Aerospike Server running as a daemon, but instead as a foreground process. You can see this in the official github DOCKERFILE.

AMC is not part of Aerospike's Docker Image. It is up to you to run AMC from the environment of your choosing.

Finally, since you have not created a custom aerospike.conf file, Aerospike Server will only respond to clients on the Docker internal network. The -p parameters are not sufficient in itself to expose Aerospike's ports to clients, you'd also need to configure access-address, if you'd want client access from outside of the docker environment. Read more about Aerospike's networking at: https://www.aerospike.com/docs/operations/configure/network/general

Answer 2

You can build your own Docker container for amc to connect to aerospike running on containers.

Here is a sample Dockerfile for AMC.

cat Dockerfile 

FROM ubuntu:xenial

ENV AMC_VERSION 4.0.13 


# Install AMC server 


RUN \
  apt-get update -y \
  && apt-get install -y wget python python-argparse python-bcrypt python-openssl logrotate net-tools iproute2 iputils-ping \
  && wget "https://www.aerospike.com/artifacts/aerospike-amc-community/${AMC_VERSION}/aerospike-amc-community-${AMC_VERSION}_amd64.deb" -O aerospike-amc.deb \
  && dpkg -i aerospike-amc.deb \
  && apt-get purge -y




# Expose Aerospike ports
#
#   8081 – amc port
#
EXPOSE 8081 

# Execute the run script in foreground mode
ENTRYPOINT ["/opt/amc/amc"]
CMD [" -config-file=/etc/amc/amc.conf -config-dir=/etc/amc"]

#/opt/amc/amc -config-file=/etc/amc/amc.conf -config-dir=/etc/amc

# Docker build sample:
# docker build -t amctest .

# Docker run sample for running amc on port 8081
# docker run -tid --name amc -p 8081:8081 amctest
# and access through http://127.0.0.1:8081

Then you can build the image:

docker build -t amctest .

and finally run it with port forwarding to port 8081:
