set max_map_count value (Linux) |

From this link The vm_max_map_count kernel setting needs to be set to at least 262144 for production use. Depending on your platform: The vm_map_max_count setting should be set permanently in /etc/sysctl.conf: To apply the setting on a live system type:

If you are using this docker image with the official mac version of docker simply go to the docker icon > preferences > advanced and slide the memory to be above 2GB. |

Hey Guys, and I still get the same error.... any ideas?? |
|
@tzookb, did you also set max map count like this comment? And possibly an env var of |
|
Thanks @yosifkit I can add this, to my docker .env file right : but where do I update the above max map? Thanks!! |

@tzookb you should use the sysctl -w command on the host machine not in the docker container. This will solve the issue. Hope this helps... |
I don't have sudo access on host machine. So How do I solve this in this case? |

@kanihal, If you have full Docker access, you have sudo access. 😉 $ sysctl vm.max_map_count
vm.max_map_count = 262144
$ docker run -it --rm --privileged --net=host --pid=host -v /:/host debian:sid chroot /host sysctl -w vm.max_map_count=262145
vm.max_map_count = 262145
$ sysctl vm.max_map_count
vm.max_map_count = 262145 |

@yosifkit Thanks it worked. host info:
BTW why are we using |
No particular reason; you could use whatever base image you want as long as it has |
@yosifkit |
@kanihal, I have no idea. I only know that elasticsearch requires a large enough As the image is working fine then I suggest heading to the Docker Community Forums, the Docker Community Slack, or Stack Overflow for further help or debugging. As a side note, if you are using the 5 series, then you will have #153 and not run into this problem; that is not true for the the 6 series and above (like the config from 6.6.0). I did manage to get it $ sysctl vm.max_map_count
vm.max_map_count = 262000
$ # ie, less than the required 262144
$ # basically this replaces the default cluster ready config
$ # and sets the config in such a way that the bootstrap checks done by elasticsearch are no longer fatal
$ # probably need a volume, not "-it --rm", etcetera
$ docker run -it --rm elasticsearch:6.6.0 sh -c 'echo "http.host: 0.0.0.0" > /usr/share/elasticsearch/config/elasticsearch.yml && exec docker-entrypoint.sh'
....

....It would probably be simpler to create an image: FROM elasticsearch:6.6.0
# cat local-config.yml
# http.host: 0.0.0.0
COPY local-config.yml /usr/share/elasticsearch/config/elasticsearch.yml
# alternative to COPY + file
RUN echo 'http.host: 0.0.0.0' > /usr/share/elasticsearch/config/elasticsearch.yml |

If someone else stumbles over this for a test system you can also disable the bootstrap checks by setting in the discovery.type: single-node |

If we are using Docker in Windows Home, we have to do the following:
|
|
My docker compose file functional! |
|
how do I run this: right before my docker containers start up (imagine that I reboot an ec2 instance). does docker-compose have a "before" hook? |
|
I'd recommend using a file in In the future, these sorts of questions/requests would be more appropriately posted to the Docker Community Forums, the Docker Community Slack, or Stack Overflow. |
