DSB Social Network - Transition and Tuning Guide

Porting Bitnami Containers: “mcrouter”

Requirements:

  • Build bitnami/memcached image for arm64 and push to Docker Hub
  • Build bitnami/memcached-exporter image for arm64 and push to Docker Hub
  • Write Dockerfile and build a mcrouter docker image for arm64 and push to Docker Hub

Step 1: Build memcached image from bitnami for arm64

  • Clone the bitnami containers repository from GitHub: Let’s build from here and open Dockerfile for editing.
git clone https://github.com/bitnami/containers.git cd containers/bitnami/memcached/1/debian-11 vim Dockerfile
  • Update the Dockerfile:

    • Update Line 14: OS_ARCH="${TARGETARCH:-amd64}" \ -> OS_ARCH="${TARGETARCH:-arm64}" \
    • Update: "Bitnami ” -> “https://anuphal.s3.amazonaws.com/${COMPONENT}.tar.gz”
    • Delete Line 30: curl -SsLf "Bitnami " -O ; \
    • Delete Line 32: sha256sum -c "${COMPONENT}.tar.gz.sha256" && \
    • Update Line 34: rm -rf "${COMPONENT}".tar.gz{,.sha256} ; \ -> rm -rf "${COMPONENT}".tar.gz; \
  • Build Dockerfile (Refer Appendix B)

  • Push to Dockerhub (Refer Appendix B)


Step 2: Build memcached-exporter image from bitnami for arm64

  • Clone the bitnami containers repository from GitHub: Let’s build from here and open Dockerfile for editing.

    • git clone “https://github.com/bitnami/containers.git” - Connect your Github account
    • cd containers/bitnami/memcached-exporter/0/debian-11
    • vim Dockerfile
  • Update the 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; \
  • Build from Dockerfile and push image to Docker Hub (Refer Appendix B)


Step 3: (Build kubectl container from bitnami/containers

  • Clone the bitnami containers repository from GitHub: Let’s build from here and open “containers/bitnami/kubectl/1.25/Debian-11/Dockerfile” for editing.

    • git clone “https://github.com/bitnami/containers.git” - Connect your Github account
    • cd containers/bitnami/kubectl/1.25/debian-11
    • vim Dockerfile
  • Update the 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; \
  • Build from Dockerfile and push image to Docker Hub (Refer Appendix B)


Step 4: Build mcrouter container from facebook/mcrouter

  • Write a Dockerfile to build mcrouter (Refer Appendix B)
  • Build Dockerfile (Refer Appendix B)
  • Push to Dockerhub (Refer Appendix B)

Step 5: Make changes to mcrouter charts

cd DeathStarBench/socialNetwork/helm-chart/socialnetwork/charts/ tar xf mcrouter-0.3.0.tgz vim mcrouter/values.yaml

  • Update Line 2:

    • Search for “bitnami” and replace with “anuphal” or your dockerhub or repository username
    • Update tag after colon ‘:’ to latest
  • Search and replace v1beta1 with v1 in the mcrouter folder. v1beta1 is deprecated since v1.16

    • “grep -inr v1beta1” will throw multiple occurrences of v1beta1 in different files
    • Replace “v1beta1” with “v1” in all related files
  • Modify configmap.yaml

    • Add Role and RoleBinding (Refer Appendix B)
vim mcrouter/templates/configmap.yaml

Step 6: Make changes to mcrouter chart

vim DeathStarBench/socialNetwork/helm-chart/socialnetwork/charts/mcrouter/charts/memcached/values.yaml
  • Clone the bitnami charts repository from GitHub

  • Open “charts/bitnami/memcached/values.yaml” for editing

    • Search for key “repository:” and replace its value from “bitnami” to “anuphal” or your dockerhub or repository username
    • Search for key “tag:” and replace its value to “latest”
  • Go back to “charts/bitnami”

cd charts/bitnami/ tar czvf mcrouter-0.3.0.tgz mcrouter/ cd DeathStarBench/socialNetwork/helm-chart/socialnetwork/charts/ rm -rf mcrouter-0.3.0.tgz file
  • Move mcrouter-0.3.0.tgz from charts/bitnami to above DeathStarBench path
mv charts/bitnami/mcrouter-0.3.0.tgz .

Step 7: Make changes to mcrouter hooks template

vim DeathStarBench/socialNetwork/helm-chart/socialnetwork/templates/hooks/mcrouter/post-install-hook.yaml
  • Update Line 11 (The line number may change as bitnami upgrades their code):
    • Search for “bitnami” and replace with “anuphal” or your dockerhub or repository username
    • Update tag after colon ‘:’ to latest
Next: Porting DeathStarBench Source Code
