I have a container with nodejs and pm2 as start command and on OpenShift i get this error on startup:
Error: EACCES: permission denied, mkdir '/.pm2'
I tried same image on a Marathon hoster and it worked fine.
Do i need to change something with UserIds?
The Dockerfile:
FROM node:7.4-alpine
RUN npm install --global yarn pm2
RUN mkdir /src
COPY . /src
WORKDIR /src
RUN yarn install --production
EXPOSE 8100
CMD ["pm2-docker", "start", "--auto-exit", "--env", "production", "process.yml"]
Update
the node image already creates a new user "node" with UID 1000 to not run the image as root.
I also tried to fix permissions and adding user "node" to root group.
Further i told pm2 to which dir it should use with ENV var:
PM2_HOME=/home/node/app/.pm2
But i still get error:
Error: EACCES: permission denied, mkdir '/home/node/app/.pm2'
Updated Dockerfile:
FROM node:7.4-alpine
RUN npm install --global yarn pm2
RUN adduser node root
COPY . /home/node/app
WORKDIR /home/node/app
RUN chmod -R 755 /home/node/app
RUN chown -R node:node /home/node/app
RUN yarn install --production
EXPOSE 8100
USER 1000
CMD ["pm2-docker", "start", "--auto-exit", "--env", "production", "process.yml"]
Update2 thanks to Graham Dumpleton i got it working
FROM node:7.4-alpine
RUN npm install --global yarn pm2
RUN adduser node root
COPY . /home/node/app
WORKDIR /home/node/app
RUN yarn install --production
RUN chmod -R 775 /home/node/app
RUN chown -R node:root /home/node/app
EXPOSE 8100
USER 1000
CMD ["pm2-docker", "start", "--auto-exit", "--env", "production", "process.yml"]
