Fix new github actions e2e failure #890

thockin · 2024-06-13T05:00:10Z

Tests worked 4 days ago, no committed changes since then. Now fails with:

testcase webhook_fail_retry: FAIL

docker: Error response from daemon: invalid config for network bridge: invalid endpoint settings:
user specified IP address is supported on user defined networks only.
See 'docker run --help'.

We have exactly one testcase that needs this (docker run --ip). It used to work and now it doesn't. It looks like maybe --ip NEVER worked but just didn't error before.

github actions fails with an error about "--ip can only be used on user-defined subnets". It looks like `--ip` never worked properly, but wasn't a hard error before. This is a simpler alternative to 11f4752 (included below), which tried using docker networks. It seems to work but is complicated and can leak resources. Needs more work. Instead, this commit just swaps out the `nc` response script on the fly, rather than restarting `nc` and trying to get the same IP. ```diff commit 11f4752 Good "git" signature for [email protected] with ED25519 key SHA256:PfQ0rwNUgsu5aRmerT0vkihWn/S3MXY3uoCPUiMdPrg Author: Tim Hockin <[email protected]> Date: Wed Jun 12 20:12:54 2024 -0700 debug test fail github actions fails with an error about "--ip can only be used on user-defined subnets" diff --git a/test_e2e.sh b/test_e2e.sh index d6ad730..b10e895 100755 --- a/test_e2e.sh +++ b/test_e2e.sh @@ -117,7 +117,7 @@ function assert_file_lines_ge() { function assert_metric_eq() { local val - val="$(curl --silent "http://localhost:$HTTP_PORT/metrics" \ + val="$(curl --silent "http://$GITSYNC_IP:$HTTP_PORT/metrics" \ | grep "^$1 " \ | awk '{print $NF}')" if [[ "${val}" == "$2" ]]; then @@ -138,6 +138,9 @@ function assert_fail() { ) } +DOCKER_SUBNET="192.168.0.0/24" +GITSYNC_IP="192.168.0.254" + # Helper: run a docker container. function docker_run() { RM="--rm" @@ -148,6 +151,7 @@ function docker_run() { -d \ ${RM} \ --label git-sync-e2e="$RUNID" \ + --network "e2e_$RUNID" \ "$@" sleep 2 # wait for it to come up } @@ -158,7 +162,8 @@ function docker_ip() { echo "usage: $0 <id>" return 1 fi - docker inspect "$1" | jq -r .[0].NetworkSettings.IPAddress + docker inspect "$1" \ + | jq -r ".[0].NetworkSettings.Networks.e2e_$RUNID.IPAddress" } function docker_kill() { @@ -278,7 +283,8 @@ function GIT_SYNC() { -i \ ${RM} \ --label git-sync-e2e="$RUNID" \ - --network="host" \ + --network "e2e_$RUNID" \ + --ip "$GITSYNC_IP" \ -u git-sync:$(id -g) `# rely on GID, triggering "dubious ownership"` \ -v "$ROOT":"$ROOT":rw \ -v "$REPO":"$REPO":ro \ @@ -308,6 +314,9 @@ function remove_containers() { | while read CTR; do docker kill "$CTR" >/dev/null done + docker network prune -f \ + --filter label=git-sync-e2e \ + >/dev/null } # @@ -2515,7 +2524,7 @@ function e2e::expose_http() { # do nothing, just wait for the HTTP to come up for i in $(seq 1 5); do sleep 1 - if curl --silent --output /dev/null http://localhost:$HTTP_PORT; then + if curl --silent --output /dev/null "http://$GITSYNC_IP:$HTTP_PORT"; then break fi if [[ "$i" == 5 ]]; then @@ -2524,23 +2533,23 @@ function e2e::expose_http() { done # check that health endpoint fails - if [[ $(curl --write-out %{http_code} --silent --output /dev/null http://localhost:$HTTP_PORT) -ne 503 ]] ; then - fail "health endpoint should have failed: $(curl --write-out %{http_code} --silent --output /dev/null http://localhost:$HTTP_PORT)" + if [[ $(curl --write-out %{http_code} --silent --output /dev/null "http://$GITSYNC_IP:$HTTP_PORT") -ne 503 ]] ; then + fail "health endpoint should have failed: $(curl --write-out %{http_code} --silent --output /dev/null http://$GITSYNC_IP:$HTTP_PORT)" fi wait_for_sync "${MAXWAIT}" # check that health endpoint is alive - if [[ $(curl --write-out %{http_code} --silent --output /dev/null http://localhost:$HTTP_PORT) -ne 200 ]] ; then + if [[ $(curl --write-out %{http_code} --silent --output /dev/null "http://$GITSYNC_IP:$HTTP_PORT") -ne 200 ]] ; then fail "health endpoint failed" fi # check that the metrics endpoint exists - if [[ $(curl --write-out %{http_code} --silent --output /dev/null http://localhost:$HTTP_PORT/metrics) -ne 200 ]] ; then + if [[ $(curl --write-out %{http_code} --silent --output /dev/null "http://$GITSYNC_IP:$HTTP_PORT/metrics") -ne 200 ]] ; then fail "metrics endpoint failed" fi # check that the pprof endpoint exists - if [[ $(curl --write-out %{http_code} --silent --output /dev/null http://localhost:$HTTP_PORT/debug/pprof/) -ne 200 ]] ; then + if [[ $(curl --write-out %{http_code} --silent --output /dev/null "http://$GITSYNC_IP:$HTTP_PORT/debug/pprof/") -ne 200 ]] ; then fail "pprof endpoint failed" fi } @@ -2568,7 +2577,7 @@ function e2e::expose_http_after_restart() { # do nothing, just wait for the HTTP to come up for i in $(seq 1 5); do sleep 1 - if curl --silent --output /dev/null http://localhost:$HTTP_PORT; then + if curl --silent --output /dev/null "http://$GITSYNC_IP:$HTTP_PORT"; then break fi if [[ "$i" == 5 ]]; then @@ -2579,7 +2588,7 @@ function e2e::expose_http_after_restart() { sleep 2 # wait for first loop to confirm synced # check that health endpoint is alive - if [[ $(curl --write-out %{http_code} --silent --output /dev/null http://localhost:$HTTP_PORT) -ne 200 ]] ; then + if [[ $(curl --write-out %{http_code} --silent --output /dev/null "http://$GITSYNC_IP:$HTTP_PORT") -ne 200 ]] ; then fail "health endpoint failed" fi assert_link_exists "$ROOT/link" @@ -3503,6 +3512,12 @@ function run_test() { set -o errexit set -o nounset set -o pipefail + docker network prune -f \ + --filter label=git-sync-e2e \ + >/dev/null + docker network create "e2e_$RUNID" \ + --subnet "$DOCKER_SUBNET" \ + --label git-sync-e2e="$RUNID" "$@" ) eval "$retvar=$?" ```
