shouldn't the current directory be the default context for "podman build"?

by Robert P. J. Day

"man podman-build" suggests that the context argument is optional: SYNOPSIS podman build [options] [context] podman image build [options] [context] ... If no context directory is specified, then Podman will assume the current working directory as the build context, which should contain the Containerfile. but if i have a directory with nothing but a Containerfile, i get: $ podman build Error: no context directory specified, and no containerfile specified $ OTOH, specifying context of current directory: $ podman build . STEP 1: FROM alpine:latest ... etc etc ... thoughts? rday

mqueue msg_max in rootless container

by Michael Ivanov

Hallo! I'm trying to run my application in podman rootless container and I stumble on following problem: my program needs /proc/sys/fs/mqueue/msg_max to be at least 256, but in running container this value is just 10. When I try to specify this parameter while running the image (--sysctl 'fs.mqueue.msg_max=256') I get the following error: Error: open /proc/sys/fs/mqueue/msg_max: Permission denied: OCI permission denied and container is not created. My host where container is being run has this parameter set to 256. How can I expose current host setting for msg_max to my container? Best regards, -- \ / | | (OvO) | Михаил Иванов | (^^^) | | \^/ | E-mail: ivans(a)isle.spb.ru | ^ ^ | |

Overriding run root "/tmp/containers-user-1253/containers" with "/home/myuser/rundir/containers" from database

by GHui Wu

I set "export XDG_RUNTIME_DIR=", so it will use /tmp/containers-user-1253/containers. But sometimes it'll use /home/myuser/rundir/containers. In debug log, there is "Overriding run root "/tmp/containers-user-1253/containers" with "/home/myuser/rundir/containers" from database". Why is this happened. time="2023-02-14T16:05:51+08:00" level=debug msg="Initializing boltdb state at /tmp/1253/share/containers/storage/libpod/bolt_state.db" time="2023-02-14T16:05:51+08:00" level=debug msg="Using conmon from $PATH: "/home/myuser/.local/container/bin/conmon"" time="2023-02-14T16:05:51+08:00" level=debug msg="Initializing boltdb state at /tmp/1253/share/containers/storage/libpod/bolt_state.db" time="2023-02-14T16:05:51+08:00" level=debug msg="Overriding run root "/tmp/containers-user-1253/containers" with "/home/myuser/rundir/containers" from database" time="2023-02-14T16:05:51+08:00" level=debug msg="Using graph driver overlay" time="2023-02-14T16:05:51+08:00" level=debug msg="Using graph root /tmp/1253/share/containers/storage" time="2023-02-14T16:05:51+08:00" level=debug msg="Using run root /home/myuser/rundir/containers" time="2023-02-14T16:05:51+08:00" level=debug msg="Using static dir /tmp/1253/share/containers/storage/libpod" time="2023-02-14T16:05:51+08:00" level=debug msg="Using tmp dir /tmp/podman-run-1253/libpod/tmp" time="2023-02-14T16:05:51+08:00" level=debug msg="Using volume path /tmp/1253/share/containers/storage/volumes" time="2023-02-14T16:05:51+08:00" level=info msg="podman filtering at log level trace"

Problems with routing in rootless podman

by Henrik Jacobsson

Hello. We are running our application in rootless podman. After some random time (a couple of hours - a couple of weeks), we lose the network connectivity into the container. Everything seems to work fine from inside the container to the rest of the world (yum/dnf, ping, curl), but it looks like the routing stops working when someone calls from the outside. I set up a netcat listener (nc -lv), and called it on localhost (worked fine) and on the tap-interface (long delays if the packet ever returned). I also set up a tcpdump in a third screen – output below. bash-4.4$ podman --version podman version 4.2.0 bash-4.4$ uname -a Linux podman-container 5.4.17-2136.315.5.el8uek.x86_64 #2 SMP Wed Dec 21 19:38:18 PST 2022 x86_64 x86_64 x86_64 GNU/Linux bash-4.4$ cat /etc/os-release NAME="Oracle Linux Server" VERSION="8.7" ID="ol" ID_LIKE="fedora" VARIANT="Server" VARIANT_ID="server" VERSION_ID="8.7" PLATFORM_ID="platform:el8" PRETTY_NAME="Oracle Linux Server 8.7" ANSI_COLOR="0;31" CPE_NAME="cpe:/o:oracle:linux:8:7:server" HOME_URL="https://linux.oracle.com/" BUG_REPORT_URL="https://bugzilla.oracle.com/" ORACLE_BUGZILLA_PRODUCT="Oracle Linux 8" ORACLE_BUGZILLA_PRODUCT_VERSION=8.7 ORACLE_SUPPORT_PRODUCT="Oracle Linux" ORACLE_SUPPORT_PRODUCT_VERSION=8.7 # Testing communication using 'localhost' inside the container - works as expected [root@NC-Test_podman-container /]# nc -lv 10370 Listening on 0.0.0.0 10370 Connection received on localhost 47218 ping from server ping from client [root@NC-Test_podman-container /]# nc -v localhost 10370 nc: connect to localhost (::1) port 10370 (tcp) failed: Connection refused Connection to localhost (127.0.0.1) 10370 port [tcp/*] succeeded! ping from server ping from client # Testing communication using hostname - "some" packets arrives, but only after a random delay of about 30-600 seconds [root@NC-Test_podman-container /]# nc -lv 10370 Listening on 0.0.0.0 10370 server Connection received on podman-container 59258 client [root@NC-Test_podman-container /]# nc -v podman-container 10370 Connection to podman-container (10.11.12.102) 10370 port [tcp/*] succeeded! client server [root@NC-Test_podman-container base_domain]# tcpdump -vv -X host podman-container and port 10370 dropped privs to tcpdump tcpdump: listening on tap0, link-type EN10MB (Ethernet), capture size 262144 bytes 12:41:49.080602 IP (tos 0x0, ttl 64, id 61404, offset 0, flags [DF], proto TCP (6), length 47) podman-container.56372 > podman-container-oob.10370: Flags [P.], cksum 0xdb21 (correct), seq 2129174302:2129174309, ack 1071210498, win 65480, length 7 0x0000: 4500 002f efdc 4000 4006 7df1 0a00 0264 E../..@.@.}....d 0x0010: 0a31 b666 dc34 2882 7ee8 9f1e 3fd9 6002 .1.f.4(.~...?.`. 0x0020: 5018 ffc8 db21 0000 636c 6965 6e74 0a P....!..client. 12:41:49.080783 IP (tos 0x0, ttl 64, id 48821, offset 0, flags [none], proto TCP (6), length 40) podman-container-oob.10370 > podman-container.56372: Flags [.], cksum 0x2039 (correct), seq 1, ack 7, win 65535, length 0 0x0000: 4500 0028 beb5 0000 4006 ef1f 0a31 b666 E..(....@....1.f 0x0010: 0a00 0264 2882 dc34 3fd9 6002 7ee8 9f25 ...d(..4?.`.~..% 0x0020: 5010 ffff 2039 0000 P....9.. 12:42:28.673431 IP (tos 0x0, ttl 64, id 49091, offset 0, flags [none], proto TCP (6), length 40) podman-container-oob.10370 > podman-container.51394: Flags [F.], cksum 0xf92e (correct), seq 946730519, ack 2284994989, win 65535, length 0 0x0000: 4500 0028 bfc3 0000 4006 ee11 0a31 b666 E..(....@....1.f 0x0010: 0a00 0264 2882 c8c2 386d f617 8832 41ad ...d(...8m...2A. 0x0020: 5011 ffff f92e 0000 P....... 12:42:28.673436 IP (tos 0x0, ttl 64, id 0, offset 0, flags [DF], proto TCP (6), length 40) podman-container.51394 > podman-container-oob.10370: Flags [R], cksum 0x27c1 (correct), seq 2284994989, win 0, length 0 0x0000: 4500 0028 0000 4000 4006 6dd5 0a00 0264 E..(..@.@.m....d 0x0010: 0a31 b666 c8c2 2882 8832 41ad 0000 0000 .1.f..(..2A..... 0x0020: 5004 0000 27c1 0000 P...'... 12:44:28.693154 IP (tos 0x0, ttl 64, id 49943, offset 0, flags [none], proto TCP (6), length 47) podman-container-oob.10370 > podman-container.56372: Flags [P.], cksum 0xcadb (correct), seq 1:8, ack 7, win 65535, length 7 0x0000: 4500 002f c317 0000 4006 eab6 0a31 b666 E../....@....1.f 0x0010: 0a00 0264 2882 dc34 3fd9 6002 7ee8 9f25 ...d(..4?.`.~..% 0x0020: 5018 ffff cadb 0000 7365 7276 6572 0a P.......server. 12:44:28.693174 IP (tos 0x0, ttl 64, id 61405, offset 0, flags [DF], proto TCP (6), length 40) podman-container.56372 > podman-container-oob.10370: Flags [.], cksum 0x2070 (correct), seq 7, ack 8, win 65473, length 0 0x0000: 4500 0028 efdd 4000 4006 7df7 0a00 0264 E..(..@.@.}....d 0x0010: 0a31 b666 dc34 2882 7ee8 9f25 3fd9 6009 .1.f.4(.~..%?.`. 0x0020: 5010 ffc1 2070 0000 P....p..
