MongoDB HA deployment with docker

Requirements

· Docker (version 17.09.0-ce used).
· Linux OS (Ubuntu 16.04 Distribution used).

Pull images (Option 1)

To pull the images from the repo:

# ./pull_containers.sh

Build images (Option 2)

To build images from local project:

# ./build_containers.sh

Run containers:

To deploy our mongodb cluster with the default configuration:

# ./run_all.sh

Check that all is ok:

To check that all is working ok:

# mongo --host 172.18.0.10 Requirement --eval 'db.Requirements.insertOne({"Granada": "Alhambra"})'
# mongo --host 172.18.0.10 Requirement --eval 'db.Requirements.find()'

If it goes well, now you have to bring down the primary mongodb:

# docker stop mongodb_1

After that, you have to request again for the content of the Requirements collection:

# mongo --host 172.18.0.10 Requirement --eval 'db.Requirements.find()'

If it does not respond in the first request, try again (the cluster has to reconfigure).
The respond must be the same ({“Granada”: “Alhambra”}).

Remove containers

To remove the containers:

# ./remove_containers.sh
