postgresql-plv8-docker-images

Docker images of PostgreSQL with PLV8 extensions installed.

Preparing a new image

  1. Decide for which version of Postgres you want to create an image with the plv8 extension. Let's use Postgres 12.10 in the example.
  2. Check in the matrix of Postgresql extension versions supported by AWS what version of the plv8 extension is supported. In our example, this is 2.13.4.
  3. Create a new directory named by a template postgresql-{postgresVersion}-plv8-{plv8Version}, e.g. postgresql-12.10-plv8-2.3.14
  4. Create a Dockerfile file inside a new directory based on the file taken from another directory. A directory with the highest version in the name will be the best choice because it will most likely work.
  5. Adjust the plv8 and Postgresql versions in the Dockerfile. 
    FROM postgres:12.10
(...)
ENV PLV8_VERSION=2.3.14
  6. Add a new image definition in the docker-compose.yml file in the root directory of this repo, e.g.: 
    postgresql-12.10-plv8-2.3.14:
  build: postgresql-12.10-plv8-2.3.14
  7. Build a docker image from a command line: 
    docker build postgresql-12.10-plv8-2.3.14
    IMPORTANT: When you build an image on Apple Mac with M1 / M2, etc. chipset, Docker will build it using linux/arm64 architecture and the build will fail because plv8 developers do not currently support this architecture. In this case, run the command below: 
    docker build --platform linux/x86_64 postgresql-12.10-plv8-2.3.14
  8. When docker finishes building an image, look for the image ID at the end of the docker build log: 
    => => writing image sha256:71119e257b8c271519293393c350b71f50210f8038dad83e0886ce0517f554e8
    alternatively, you can find the image ID by running a command: 
    docker images
    and checking the IMAGE ID column, e.g. 
    REPOSITORY   TAG      IMAGE ID       CREATED          SIZE
<none>       <none>   71119e257b8c   23 minutes ago   420MB
  9. Tag a new docker image with an appropriate name containing Postgresql and plv8 extension versions, e.g.: 
    docker tag 71119e257b8c draakhan/postgresql-plv8:12.10-2.3.14
    You can check if it is tagged correctly by running again docker images command: 
    REPOSITORY                 TAG            IMAGE ID       CREATED             SIZE
draakhan/postgresql-plv8   12.10-2.3.14   71119e257b8c   About an hour ago   420MB
  10. Login to your docker repository (by default, it is Docker Hub) using docker login command and then push the tagged image to the Docker Hub: 
    docker push draakhan/postgresql-plv8:12.10-2.3.14
  11. Now, you're ready to use the uploaded image in your project's Dockerfile by adding this statement: 
    FROM draakhan/postgresql-plv8:12.10-2.3.14
