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.

Copy
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

Copy
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)

Copy
vim mcrouter/templates/configmap.yaml

Step 6: Make changes to mcrouter chart

Copy
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”

Copy
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

Copy
mv charts/bitnami/mcrouter-0.3.0.tgz .

Step 7: Make changes to mcrouter hooks template

Copy
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
