I'm trying to formulate a docker healthcheck that restarts the container if the word FATAL in found in a certain log file. Something similar to this except with grep.

test: ["CMD-SHELL", "curl -f http://localhost || exit 1"]

Something like:

test: ["CMD-SHELL", "grep -i 'fatal' /var/log/log.txt || exit 1"]

Would that work?

My goal is to have 2 docker containers:

• nginx container (based on nginx:latest) to work as reverse proxy
• container with static website (based on nginx:alpine)

Later I will add 1+ .net core backend services (not important for now). Currently when I try to access my webserver using public ip address, I get 502 Bad gateway. Here is my current configuration:

I have a docker-compose with a 'db' and 'web' containers. The db is a mysql:8.0 image, and the web is a python:3.9-slim.

If I try to connect to the MySQL server inside the db container, it works. But not if I try it inside the web container, from where I get the following error:

Hi I am trying to run ebtables within docker however none of the ebtables rules are being hit.

I have strange virtual (docker bridges) networking condition

I have two dockers connected to the same bridge via docker-compose. One docker is "probe" and one is "injector". Injector uses tcpreplay to replay capture and "probe" should receive it via tcpdump. Needless to say the capture replayed does not have any relation to IPs or macs of the NICS attached to the bridge. pinging is working fine b ...

Let me start be saying I'm not an network expert. That being said, I'd need some help here as I'm breaking my head on this issue for two days now. I have several questions but will focus only on one specific one.

In my base configuration I have a few services with restart: always and in my override configuration I have those services with restart: "no", but when I reboot the host the containers are started up again. I'm expecting the containers to still be stopped, am I missing something here?

I've just installed booksonic-air through docker compose and when running curl http://127.0.0.1:4040 i get Connection reset by peer error.

Docker container looks like listening to 0.0.0.0 address so I should be able to access from the host OS.

Does anyone know how could I solve it?

I've installed only Hasura and a Postgres database (yes yes, I'll change it) in 1 docker container each. The containers themselves don't use much space, but my overall storage space is rapidly being used up each passing day! I have no idea why, I'm pretty new to this.

I am running my private Nextcloud instance using docker (docker-compose). I tried to upgrade to a newer Nextcloud version but did not realize I was not supposed to skip a major version (from 21 to 23). Now I cant start it at all:

I'm using docker containers to host a web app. I have three main containers: MySQL, flask and Nginx. The first two work as expected and the latter seems to be working fine as no error is displayed in the docker-compose startup.

I use Docker to implement a Nextcloud service. For this, I use the official nextcloud-apache image, an Nginx reverse proxy, certbot, and MariaDB. Nothing special, really.

My docker instance runs in swarm mode. All containers run together with the manager on the same host with only one replica for each service, standard overlay network(s). The swarm is started by using a standard compose file.

Got a question about docker contexts, Fellas.

I have my user theuser who belongs to the groups docker and systemd-coredump. When I login via ssh I can see via the groups command that I do indeed have the systemd-coredump group. The strange thing is my docker container (running as theuser) can not read a file that is set to RW for the systemd-coredump group.

Should I need to restart the docker service to fix this or is a complete system reboot needed? ...

Is there a de-facto 'standard' for the gateway address on class C subnets?

Asking because I've been fighting a docker-compose issue with macvlans where it assumes the gateway is always at 192.x.x.1, while the actual gateway is 192.x.x.251

I'm running a container with docker-compose on a Linux VPS (Ubuntu 20.04). I want the container to be accessible only via a VPN (ie: the container ports are not exposed on the host to the Internet and the container only accepts traffic from 127.0.0.1 and the docker network) so I am thinking of setting up a VPN server on the VPS. I would like to understand if it's feasible and get suggestions on how to i ...

I administer a few Debian servers with Docker CE installed and docker-compose orchestrating several services (roughly 20 containers per machine)..

Every single service is configured with restart: always in docker-compose. However, there are random services (usually 1-2 per machine) that shut down correct but do not restart during a host reboot. This behaviour is completely random. Sometimes all services ...
