I'm building a dockerfile. But I meet a problem. It says that :
/bin/sh: 1: mongod: not found
My dockerfile:
FROM mongo:latest
FROM node
RUN mongod
COPY . .
RUN node ./scripts/import-data.js
Here is what happen when docker build:
Sending build context to Docker daemon 829.5MB
Step 1/8 : FROM rabbitmq
---> e8261c2af9fe
Step 2/8 : FROM portainer/portainer
---> 00ead811e8ae
Step 3/8 : FROM docker.elastic.co/elasticsearch/elasticsearch:6.5.1
---> 32f93c89076d
Step 4/8 : FROM mongo:latest
---> 5976dac61f4f
Step 5/8 : FROM node
---> b074182f4154
Step 6/8 : RUN mongod
---> Running in 0a4b66a77178
/bin/sh: 1: mongod: not found
The command '/bin/sh -c mongod' returned a non-zero code: 127
Any idea ?
The problem is that you are using two FROM
instructions, which is referred to as a multi-stage build
. The final image will be based on the node
image that doesn't contain the mongo
database.
* Edit *
here are more details about what is happening:
FROM mongo:latest
mongo:latest
FROM node
node:latest
. The previous image is just standing there...RUN mongod
COPY . .
RUN node ./scripts/import-data.js
mongod
and the other commands in your final image that is based on node
(which doesn't contain mongo)
