How to configure Percona MongoDB Replicaset, Percona Backup Manager, Backup Agent using Docker and perform Replicaset backup, restore usi...
In this blog post, i will walk you through the steps required to containerize Percona Server for MongoDB, Percona Backup Manager, and Agent from source and configure cloud-native S3(Simple Storage Service) compatible distributed object storage MINIO to backup and restore Percona MongoDB snapshot backups.
Prerequisites
Ensure the below binaries are installed before starting the setup and configuration
Docker or Podman to containerize Percona MongoDB replicaset and PBM Agent Docker Compose Golang compiler – Build Percona Backup Manager binaries Portainer (Optional) – Intuitive UI for container configuration and monitoring Let us perform the below steps to set up PSMDB Replicaset; PBM Agent; Minio, S3 compatible bucket, and PBM configuration to perform backups and restores from the bucket.
Steps
- Create the Docker environment file with Docker Image, tag, port, and replicaset information. Save the file as .env in the working directory
MONGODB_IMAGE=percona/percona-server-mongodb
MONGODB_VERSION=5.0
MONGO1_PORT=0.0.0.0:15000
MONGO2_PORT=0.0.0.0:15001
MONGO3_PORT=0.0.0.0:15002
MONGODB_PORT=27017
MONGODB_DOCKER_NETWORK=mongo_net
RS_NAME=rs1
- Create keyFile , Dockerfile and download percona-backup-manager source code in the working directory
$ git clone https://github.com/percona/percona-backup-mongodb.git
ARG MONGODB_VERSION
ARG MONGODB_IMAGE
FROM ${MONGODB_IMAGE}:${MONGODB_VERSION}
USER root
COPY keyFile /opt/keyFile
RUN chown mongodb /opt/keyFile && chmod 400 /opt/keyFile && mkdir -p /home/mongodb/ && chown mongodb /home/mongodb
USER mongodb

- Setup PBM or compile PBM from the source repository
$ sudo apt-get install -y libkrb5-dev
$ cd percona-backup-mongodb
$ make build
$ make install
- create pbm_config.YAML to be used for configuring PBM for using MINIO
storage:
type: s3
s3:
endpointUrl: http://192.168.50.113:7000
bucket: pbm
credentials:
access-key-id: "minioadmin"
secret-access-key: "minioadmin"
- Configure PBM
$ ./pbm config --file /home/robin/dev/psmdb/pbm_config.yaml --mongodb-uri="mongodb://bcp:test1234@192.168.50.113:15000/?replSetName=rs1"
- Validate agent container logs and run the pbm list command. If MINIO is configured successfully, agent container logs shouldn’t log any errors.
