I have acceptance tests set up with ddev. They get run locally on ddev composer cookieman:test. I would like to use the same setup with Github actions.
Did anybody have any luck with ddev in Github actions/workflow? I am getting until here where ddev's healthcheck fails:
...

I tried
using Ubuntu 16.04
fully upgrading all packages on Ubuntu 16.04/18.04
configuring ddev like that:
run: ddev config global --router-bind-all-interfaces=truerun: ddev config global --omit-containers=dba,ddev-ssh-agentchanging to unprivileged router ports (settings router_http_port, router_https_port in config.yaml)
If I force it to continue with ddev start || exit 0 I can see containers up and running:
- run: docker ps || exit 0

curl 127.0.0.1 yields the default nginx start page (while I would expect '503: No ddev back-end site available')
curl 127.0.0.1/healthcheck yields a 404
So far my conclusion is: ddev-router is reachable but its nginx does not have the appropriate configuration (no servers are inside upstream in /etc/nginx/conf.d/default.conf). Thus ddev only runs the pre-start hook form config.yaml. post-start is not reached.
You can see the output of the last runs here https://github.com/dmind-gmbh/extension-cookieman/actions?query=branch%3Afeat%2Facceptance-tests
EDIT/AMEND:
This is the (mal-)generated /etc/nginx/conf.d/default.conf from ddev-router:
# If we receive X-Forwarded-Proto, pass it through; otherwise, pass along the
# scheme used to connect to this server
map $http_x_forwarded_proto $proxy_x_forwarded_proto {
default $http_x_forwarded_proto;
'' $scheme;
}
# If we receive X-Forwarded-Port, pass it through; otherwise, pass along the
# server port the client connected to
map $http_x_forwarded_port $proxy_x_forwarded_port {
default $http_x_forwarded_port;
'' $server_port;
}
# If we receive Upgrade, set Connection to "upgrade"; otherwise, delete any
# Connection header that may have been passed to this server
map $http_upgrade $proxy_connection {
default upgrade;
'' close;
}
# Apply fix for very long server names
server_names_hash_bucket_size 128;
# Default dhparam
# ssl_dhparam /etc/nginx/dhparam/dhparam.pem;
# Set appropriate X-Forwarded-Ssl header
map $scheme $proxy_x_forwarded_ssl {
default off;
https on;
}
rfay mentioned a miscommunication between the ddev-router and the underlying docker daemon via sockets.
I came to the conclusion that the problem is with docker-gen.
In the first line of the template (https://github.com/drud/ddev/blob/master/containers/ddev-router/nginx.tmpl or also jwilder's https://github.com/jwilder/nginx-proxy/blob/master/nginx.tmpl) the .Docker.CurrentContainerID is empty which seemed to happen to some people in some contexts https://github.com/jwilder/docker-gen/issues/196#issuecomment-225412753.
The suggested removal of '-only-exposed' did not work for me. I changed the template a bit instead to not rely on the container and that was it.
:)
This is still a bit dirty and only a Proof-of-concpet:
this is the changed template https://github.com/jonaseberle/github-action-setup-ddev/blob/master/.ddev/patches/ddev-router/nginx.tmpl (compare the upstream {} section where I removed the check if containers are on the same network with the router)
In the workflow I do
ddev start || exit 0 # this will fail and also not execute any post-start hooksdocker cp nginx-debug.tmpl ddev-router:/app/nginx-debug.tmpldocker exec ddev-router sh -c "docker-gen -only-exposed -notify 'sleep 1 && nginx -s reload' /app/nginx-debug.tmpl /etc/nginx/conf.d/default.conf"Not decided how to move on from here. Maybe @rfay would have an idea how to change the nginx-template. Or I will use a custom Dockerfile for the ddev-router with a docker-compose.ddev-router.yaml to change the file just for the Github actions run...
EDIT/AMEND:
The shorter and tested version of this is:
ddev start || docker cp .ddev/patches/ddev-router/nginx.tmpl ddev-router:/app/nginx.tmplddev start - this triggers a container restart and thus a docker-gen run
