i displaying map @ android application (google maps api v2). want manipulate map in order show specific location, zoom , marker. can give example of manipulation mapfragment to map instance in code this: map = ((supportmapfragment) getsupportfragmentmanager().findfragmentbyid(r.id.map)).getmap(); or: map = ((mapfragment) getfragmentmanager().findfragmentbyid(r.id.map)).getmap(); depending on whether used supportmapfragment or mapfragment in xml file. then add marker it: marker newmarker = map.addmarker(new markeroptions().position(latlng).title("marker title").icon(bitmapdescriptorfactory.fromresource(r.drawable.marker_for_map_purpul))); to zoom map: cameraposition cameraposition = new cameraposition.builder().target(latlng).zoom(14.0f).build(); cameraupdate cameraupdate = cameraupdatefactory.newcameraposition(cameraposition); map.movecamera(cameraupdate);

i want run docker watchtower automatically upgrade docker containers whenever push new version private registry. however, watchtower doesn't find containers in private registry. does know how run watchtower private docker registry? watchtower supports docker hub private registry, not off-site registries quay or gitlab. an alternative might use webhook , include http request endpoint whatever ci/cd platform you're using. that way, instead of checking updates, can ping endpoint whenever change made, , auto-update. it's push rather pull, can achieve similar effect. an example script running web server might be: #!/bin/bash docker pull [your-registry][repo]:latest docker stop [repo-name] docker rm [repo-name] docker run -d --name [repo-name] -p 80:4000 --restart [your-registry][repo]:latest it's not slickest deployment method. you're better use dedicated ci/cd provider in production can better orchestrate build, testing , deployment pipeline....
