in this example, I copy wait-for-it.sh inside /app/wait-for-it.sh But, I don't want to save wait-for-it.sh in my local directory. I want to download it using curl and then copy into /app/wait-for-it.sh
FROM prismagraphql/prisma:1.34.8
COPY ./wait-for-it.sh /app/wait-for-it.sh
RUN chmod +x /app/wait-for-it.sh
ENTRYPOINT ["/bin/sh","-c","/app/wait-for-it.sh mysql:3306 --timeout=0 -- /app/start.sh"]
What I have tried is this, but how can I get the wait-for-it.sh after downloading the file using curl command:
FROM prismagraphql/prisma:1.34.8
FROM node:11-slim
RUN apt-get update && apt-get install -yq build-essential dumb-init
RUN curl -LJO https://raw.githubusercontent.com/vishnubob/wait-for-it/master/wait-for-it.sh
COPY wait-for-it.sh /app/wait-for-it.sh
RUN chmod +x /wait-for-it.sh
ENTRYPOINT ["/bin/sh","-c","/wait-for-it.sh mysql:3306 --timeout=0 -- /app/start.sh"]
Based on your comments below, you may try this one:
FROM prismagraphql/prisma:1.34.8
RUN apk update && apk add build-base dumb-init curl
RUN curl -LJO https://raw.githubusercontent.com/vishnubob/wait-for-it/master/wait-for-it.sh
RUN cp wait-for-it.sh /app/
RUN chmod +x /wait-for-it.sh
ENTRYPOINT ["/bin/sh","-c","/wait-for-it.sh mysql:3306 --timeout=0 -- /app/start.sh"]
Note: You need to use cp command as you want to copy the script from one location to another within your container's filesystem.
You can also confirm the presence of your script and other files/dirs in the /app folder by running the command:
$ docker run --rm --entrypoint ls waitforit -l /app/
