Hi,
I’m trying to learn docker while running 4 VMs with windows server 1709 and docker version 17.09.2-ee-7.
I’m currently trying to run a docker service in a docker swarm with a published port … but the published port doesn’t seem to be accessible … and don’t understand why, internal routing problem or whatever …?
I don’t get an answer on port 8080 even when connecting locally from the node currently running the image with f.ex “Invoke-Webrequest” (as windows server 1709 is without GUI).
The 4 VMs are part of the same swarm (1 manager + 3 workers), the manager hostname is “DOCKER”.
C:\Users\Administrator>docker node ls
ID HOSTNAME STATUS AVAILABILITY MANAGER STATUS
4n96lkxy2hf2tfja391bunch8 * DOCKER Ready Active Leader
wi2wkcrpo3ae8pol7lp68ne08 DOCKER2 Ready Active
xrx1to91p0dt9id1ji58ss5a9 DOCKER1 Ready Active
ywlqqzyulav3wr0lztbikioqi DOCKER3 Ready Active
I created a service running a windows container with tomcat in it, and published the port 8080:
docker service create -d --name tomcat -p 8080:8080 192.168.5.130/tomcat
C:\Users\Administrator>docker service ls
ID NAME MODE REPLICAS IMAGE PORTS
mjmv3wjhsf9g tomcat replicated 1/1 192.168.5.130/tomcat:latest *:8080->8080/tcp
C:\Users\Administrator>docker service ps tomcat
ID NAME IMAGE NODE DESIRED STATE CURRENT STATE ERROR PORTS
nguiv29tqz55 tomcat.1 192.168.5.130/tomcat:latest DOCKER Running Running 35 minutes ago
What’s already strange is that “docker service ps tomcat” does not show any published port but “docker service ls” does show published port … anyhow.
Here is only a snip that the service is running:
C:\Users\Administrator>docker service logs tomcat
tomcat.1.nguiv29tqz55@DOCKER |
tomcat.1.nguiv29tqz55@DOCKER | C:>set CATALINA_HOME=c:\apps\tomcat
tomcat.1.nguiv29tqz55@DOCKER |
tomcat.1.nguiv29tqz55@DOCKER | C:>c:\apps\tomcat\bin\catalina.bat run
tomcat.1.nguiv29tqz55@DOCKER | Using CATALINA_BASE: “c:\apps\tomcat”
tomcat.1.nguiv29tqz55@DOCKER | Using CATALINA_HOME: “c:\apps\tomcat”
tomcat.1.nguiv29tqz55@DOCKER | Using CATALINA_TMPDIR: “c:\apps\tomcat\temp”
tomcat.1.nguiv29tqz55@DOCKER | Using JRE_HOME: “c:\apps\java\jre”
tomcat.1.nguiv29tqz55@DOCKER | Using CLASSPATH: “c:\apps\tomcat\bin\bootstrap.jar;c:\apps\tomcat\bin\tomcat-juli.jar” …
It works perfectly when simply running the same image with “docker run -d -p 8080:8080” etc, everything does work fine when running the image that way! I can access port 8080 etc.
Just in case, someone asks, the windows firewall is off!
:\Users\Administrator>netsh advfirewall show currentprofile
Public Profile Settings:
State OFF
Any clues whats wrong or why I can’t access the published port?
Thanks a lot!
Didier
