Porting Bitnami Containers: “mongodb-sharded”

Step 1:

  • Clone the bitnami containers repository and open “mongodb-sharded” Dockerfile for editing.
git clone https://github.com/bitnami/containers.git vim containers/bitnami/charts/mongodb-sharded/6.0/debian-11/Dockerfile

Step 2:

  • Update location of the S3 Bucket or Repo mentioned previously in the Dockerfile
  • Replace the Stacksmith URL given in the Dockerfile with the custom URL of the S3 Bucket or Repository where the packages have been stored
  • Other changes include:
    • Update Line 14: OS_ARCH="${TARGETARCH:-amd64}" \ 🡪 OS_ARCH="${TARGETARCH:-arm64}" \
    • Update: "Bitnami” -> “https://anuphal.s3.amazonaws.com/${COMPONENT}.tar.gz”
    • Update Line 34: curl -SsLf "Bitnami " -O ; \
    • Delete Line 36: sha256sum -c "${COMPONENT}.tar.gz.sha256" && \
    • Update Line 38: rm -rf "${COMPONENT}".tar.gz{,.sha256} ; \ 🡪 rm -rf "${COMPONENT}".tar.gz; \

Step 3:

  • Build the mongodb-sharded docker image (Refer Appendix B)
  • Push to Dockerhub or private repository (Refer Appendix B)

Step 4:

  • In the already cloned repository of “containers”, we will now build “bitnami-shell”
cd containers/bitnami/bitnami-shell/11/debian-11 vim Dockerfile
  • Update Line 14: OS_ARCH="${TARGETARCH:-amd64}" \ 🡪 OS_ARCH="${TARGETARCH:-arm64}" \
  • Save the changes
  • Build the bitnami-shell docker image (Refer Appendix B)
  • Push to Dockerhub or private repository (Refer Appendix B)

Step 5:

  • In the already cloned repository of bitnami “containers”, we will now build “mongodb-exporter”. This package is originally from github repository “percona” and forked by “bitnami”
cd containers/bitnami/mongodb-exporter/0/debian-11 vim Dockerfile
  • Update Line 14: OS_ARCH="${TARGETARCH:-amd64}" \ 🡪 OS_ARCH="${TARGETARCH:-arm64}" \

  • Update: "Bitnami ” -> “https://anuphal.s3.amazonaws.com/${COMPONENT}.tar.gz”

  • Delete Line 29: curl -SsLf "Bitnami " -O ; \

  • Delete Line 31: sha256sum -c "${COMPONENT}.tar.gz.sha256" && \

  • Update Line 33: rm -rf "${COMPONENT}".tar.gz{,.sha256} ; \ 🡪 rm -rf "${COMPONENT}".tar.gz; \

  • Save the changes

  • Build the mongodb-exporter docker image (Refer Appendix B)

  • Push to Dockerhub or private repository (Refer Appendix B)


Step 6:

  • Modify the mongodb-sharded helm chart, tar the package and copy to DeathStarBench
cd charts/bitnami/mongodb-sharded vim values.yaml
  • Modify following lines (Use your Dockerhub username instead of anuphal. Please note that line numbers may differ in latest updates in Github repository):
    • Line 77: repository: anuphal/mongodb-sharded
    • Line 78: tag: latest
    • Line 244: repository: anuphal/bitnami-shell
    • Line 245: tag: latest
    • Line 475-479: enabled: false (This is for persistence.enabled=True)
    • Line 1245: enabled: false (This is for persistence.enabled=True)
    • Line 1539: repository: anuphal/mongodb-exporter
    • Line 1540: tag: latest
cd .. tar czvf mongodb-sharded-6.0.1.tgz mongodb-sharded/ git clone https://github.com/delimitrou/DeathStarBench.git #If an older version of mongodb-sharded-x.y.z.tgz already exists in the charts directory, #then please delete it and keep the new tgz in its place mv mongodb-sharded-6.0.1.tgz DeathStarBench/socialNetwork/helm-chart/socialnetwork/charts/
